Alkali Metals - Properties of Element Groups

Alkali Metals - Properties of Element Groups Learn about the properties of the alkali metals, one of the element groups: Location of the Alkali Metals on the Periodic Table The alkali metals are the elements located in Group IA of the periodic table. The alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium. Alkali Metal Properties The alkali metals exhibit many of the physical properties common to metals, although their densities are lower than those of other metals. Alkali metals have one electron in their outer shell, which is loosely bound. This gives them the largest atomic radii of the elements in their respective periods. Their low ionization energies result in their metallic properties and high reactivities. An alkali metal can easily lose its valence electron to form the univalent cation. Alkali metals have low electronegativities. They react readily with nonmetals, particularly halogens.

Creationalism Vs Evolution Essays - Pseudoscience, Denialism

Creationalism Vs Evolution Essays - Pseudoscience, Denialism Creationalism Vs Evolution Creationism vs. Evolution The majority of people in this world believe that a spiritual being created earth. In fact, most religions and cultures believe the universe was created by a 'creative hand,' either a sky god or some other physical object (Encarta 1). Think of it, as a trial to see which will win, creation or evolution. It has been the most argued debate in all of history, but creationism is more logical than evolution. To first understand what creation is about, we have to know what creation is. The Bible defines creation as the action by God that brought the universe and all its contents into being. The Bible also states, God created great whales and every living creature that moveth, and so God created man in his own image, in the image of God created he him; male and female created he them (Genesis 1:21, 27). To Doug LaPointe, the author of Top Evidences against the Theory of Evolution, there are nine articles of evidence pointing weaknesses in evolution, or strong points in creation. The first evidence is that there are no links between the fossil record and present times; therefore, there is nothing to show that evolution actually happened. Second, that natural selection cannot advance an organism to a higher order. The third being that although evolutionists believe life just came about, matter resulted from nothing, and humans evolved from animals, all of these are against scientific and nat ural understandings. Fourth, even though evolutionists present them as if they were, the hominids' bones and skull records, for example the famous Lucy, the finds are unrevealing and inconsistent. The fifth and sixth articles of evidence are the nine out of 12 hominids that evolutionists use are really extinct apes, and the other three are modern human beings and not part ape. This would conclude that all of the twelve 'hominids' are something other than hominids and are not half-human, half-ape. Evidence seven and eight show that natural selection has practical, social, and logical inconsistencies. The last evidence says that the rock strata finds are better explained by a universal flood than by evolution, which would show yet more proof in the Bible (LaPointe 1-2). Michael Behe, author of the recent bestseller Darwin's Black Box, states, I was amazed that people believe in evolution when there was this clear argument against it (Behe 3). At first Darwinism was taught at schools, but there were so many flaws that these ideas were turned down, and a different form of evolution was taught. The new form was then taught along with a type of scientific creation (Encarta 2). This shows that schools feel that Darwin was wrong, and Darwin is evolution's top scholar. In order to disprove a way of thinking we must first know what we are trying to disprove. The definition of evolution is the complex process by which living organisms originated on earth and have been diversified and modified through sustained changes in form and function (Encarta 2). Thomas Robert Malthus first stated that the human population was growing too fast for the food supply. This, he said, Is regulated by disease, famine, and war (Infopedia 1). Darwin applied this to animals and plants and came up with the theory of evolution by natural selection. His theory stated that the children of a species intensely compete for survival. Those young that survive to produce the next generation tend to be embodying favorable natural variations and these variations are passed on by heredity. Therefore, each generation will improve adaptively over the preceding generations, and this gradual and continuos process is the source of the evolution of the species (Infopedia 1-2). The notion th at populations of organisms can be transformed over generations into descendant population of different kinds has been suggested repeatedly since the early-recorded history of ideas, but if you trace all the species back to their origin, you would get one object. Now the real part of this argument is right here. How did that one object come into being? It couldn't have happened by mere chance. It did not always exist so there had to be nothing before it. If there was nothing before it, how was it created?

Female Economy Essay Example | Topics and Well Written Essays - 2000 words

Female Economy - Essay Example Research suggests that private wealth in America is most likely to grow by sixty percent in the year 2020 (Silverstein & Sayre, 48, 2009). It also suggests that fifty percent of this wealth would go to women. Although women have contributed positively in several fields, yet they experience discrimination and are often underestimated. They are often labeled, differentiated on basis of age or salary, characterized on basis of typical women concept or are incompetent as compared to men. This paper seeks to analyze the issue of gender differentiation and discrimination in the business domain in the lights of broad and diverse academic resources. Frequently, women are discriminated and often underestimated because of several reasons including chauvinist viewpoints, opposing and clashing policies, stereotyped, discrimination on basis of age, etc. Frequently, they are considered to be incompetent as compared to their male counterparts. Research suggests that in financial institutions, women are most likely to experience such characterizations and differentiations (Silverstein & Sayre, 52, 2009). Females in the financial industry and its institutions have made massive attempts and struggles in order to advance in their careers. However, it should be noted that women in the financial domain have the necessary education as well as the experience, yet they do not get promotions because of constant stereotype, labeling and the general culture of the corporate. Research suggests that women employed in financial services are often underestimated and their supervisors and colleagues often talk to them as if they do not have the basic knowledge on the subject.

Tessellation Pattern Essay Example | Topics and Well Written Essays - 500 words

Tessellation Pattern - Essay Example With vivid lines and basic definite shape, I find it conducive to come up with a tessellation of the ‘barking dog’ for its concrete details can be readily visualized to end up with sharp geometric tessellated form. It is more convenient I suppose to tessellate with straight rather than curved edges of the model in the process. Using MS Paint of the Windows accessories, I first cropped the image to make a barking dog-pattern then copied and pasted the same pattern in a row. The initial transformation would be to translate each common figure vertically then reflect it about the vertical axis so as to show a row of barking dog images on top and at the bottom of the one bearing the original pattern. In this manner, the tessellation design consists of rows in original and reverse positions of the barking dog image alternating each other in two shades – brown and pink. By horizontally flipping a line of mass generated figure with a row of the first orientation placed on top of the second, there emerges ease in yielding a sight of the entire object. Monotonousness is further reduced in this technique since transforming by means of translating reflections creates spatial balance at least, if not symmetry. It would feel as if the tessellated product is less complex in view especially that in between the sol id pink and the solid brown, an external structure cut-out that traces the source pattern also alternates in solid shades of maize and blue gray on application of the same transformation scheme.

The people around him Essay Example for Free

The people around him Essay These two poems are written about very different subjects but they both explore the theme of betrayal. In the first poem ‘Havisham’, the poet Carol Anne Duffy uses Mrs. Havisham, a fictional character from the well know novel ‘Great Expectations’ by Charles Dickens, as her extended metaphor for betrayal. In the second poem ‘Kid’ by Simon Armitage, the poet presents the theme of betrayal from a slightly different perspective using ‘Batman and Robin’ as his literary conceit. Both Havisham and Kid feature literary conceits through which the poets convey the characters thoughts to the reader. In Havisham, Duffy uses her chosen metaphor as the title. This makes the theme of betrayal known to the reader from the very start of the poem. Duffy asexualises the main character in the title through the absence of the pronoun â€Å"Mrs†. This puts extra emphasis on Mrs. Havisham’s metaphoric significance. In kid, Armitage uses the extended metaphor (Batman and Robin) to sarcastically influence the speakers’ role reversal of his childhood relationship with his stepfather who left him and his mother, to be in a relationship with another woman. Both poems use strong plosives in the opening line of the poem. Havisham starts off with the phrase â€Å"Beloved sweetheart bastard†. The repetition of the letter ‘b’ gives the poem an immediate aggressive tone and evokes anger. This phrase is also an oxymoron; the poet is expressing the characters unhealthy state of mind through the polarisation of feeling. This is a result of these two feeling, love and hate, are irreconcilable, and yet both experienced by the speaker to their extremes. Simon Armitage in kid also employs plosives to emphasise the anger and violence expressed throughout the poem examples include, â€Å"Batman, big shot† and â€Å"punching the palm of your hand†. Therefore, both poems use plosives in order to gain the same effect, emphasis on aggression and anger. Clothing is another common device used by both poets to express the characters state of mind. In Havisham the speaker seems to use clothing to convey a deeper meaning to the reader. â€Å"Loves hate behind a white veil† This oxymoron presents two overwhelming contradictory emotion. This shows that although the speaker is angry there is also a more sophisticated side to her. However in kid, the description of clothing is far less sophisticated; â€Å"now I’ve doffed that off-the-shoulder / Sherwood-forest-green and scarlet number for a pair of jeans and crew-neck jumper† . The speaker in kid evaluates his adulthood through his clothing, which shows that he does not operate well in society. The clothes that belong to childhood is the â€Å"Sherwood-forest-green and scarlet number† and the â€Å"pair of jeans and crew neck jumper† belong to adulthood. The speaker shows immaturity by describing his adulthood in terms of external virtues. This would seem fairly mundane in contrast to Havisham, which refers to clothing as part of an intelligent literary device, which subsequently has an effect on the reader. Enjambment is used in both poems, with each poet using this technique to create different effects on the reader. In Havisham, Duffy uses enjambment to build up dramatic tension in the poem. The enjambment used in Havisham goes against normal structure in poetry; â€Å"who did this / to me?†, the effect that is created by the thoughts of the speaker running over from one line to the other, emphasises the great anger felt by the speaker at this point. This use of enjambment is doubly useful, in this case as the overall effect of the enjambed lines is that the idea takes the form of a rant. Armitage creates a mood of aggression in Kid, partly caused by the structure of the poem. Kid is presented in four long periodic sentences with multiple sub-clauses, enjambed over nearly every line. One of the many examples can be seen on line one over to line two were the speaker says â€Å"when you gave the order / to grow up†. The emjabments used in kid also add to the menacing tirade in the poem. In Havisham the structure of the poem resembles that of natural speech. This results in the poem being more naturalistic. At the end of the poem Duffy uses the breakdown in rhythm, â€Å"b-b-b-breaks† to emphasise the speaker’s emotions. By adding in this caesura Duffy shows the disintegration of language, which connotes the breakdown of mind and the unstable mental state of the speaker as a result of the betrayal. Similarly in Kid, Simon Armitage also uses caesura’s to emphasise some key words and themes within the poem, â€Å"I’m taller, harder, stronger, older†. As well as adding greater emphasis to the words, the use of commas between each word breaks up the rhythm of the poem and similarly to Havisham makes the poem exceed the boundaries of normal poetry. This causes the poems to take on the form of a rant. Language devices are used in both poems to enhance the build up of tension. In Havisham, Duffy uses alliteration to build up tension and as stated above, show the unhealthy state of mind of the speaker. The example of this is â€Å"b-b-b-breaks†, this shows the feelings of the speaker mounting up inside her, and she has difficulty getting them out. Her hesitancy in this case could also allude to the speaker’s shamefulness of herself and the state she is in. Duffy also uses sibilance to enhance this effect, â€Å"Spinster, I stink†, this also could allude to the same effect as previously in which the speaker is ashamed of herself. The term spinster refers to unmarried women of marriageable age, and unlike bachelor has negative connotations. This use of sibilance crates a very real effect to the poem the reader can hear, see and smell Havisham in their mind. The assonance found in the second stanza, â€Å"cawing Nooooo at the wall†, implies that Havisham has been re-living in her mind the past events in her life, something that is often not psychologically healthy. The significant literal device found in Kid is the use of repetitive assonance which in this case is all the lines ending in ‘r’: â€Å"order wander yonder rather corner †. These assonances conjures up an ‘index finger pointing belligerently at the interlocutor’. The resulting effect is that of mounting anger and violence in the speaker. In conclusion Duffy lends pathos and a tragic dimension to her character. In order to have a tragic dimension in a character, the character needs to have experienced some sort of tragic event. For Havisham this was the betrayal which causes her to be totally self-aware. As a result this event will manifest itself in to the character of the speaker. This will cause the reader to sympathise with the speaker. In Kid, Armitage presents a character who seeks to measure himself favourably at someone else’s expense. This makes it much harder for the reader to sympathize with the speaker in Kid than in Havisham. As a result of this I feel that the speaker in Havisham is far more captivating than the one in Kid. This is mainly due to the effect the tragic event of betrayal suffered by the reader, has affected her behaviour. This in conjunction with the various stylistic and linguistic features in the poem make Havisham a more powerful and effective poem.

Geologist :: essays research papers fc

Geologist The goal in mineral exploraion is to find imperious meatless. It’s what they call Ore. Ore is a mineral that have a lot of value. To find ore you want to identify target areas. Overtime narrow it down and pin point the ore of the minerals. The way geologists do this is first they would look at geological maps that show worth different rock types. Sometimes they use maps that people have already made. Geologist also uses geophysical maps to find out the different properties of rocks. Geologist use magnetic instruments to find out were magnetic rocks are. The rocks that have metal in them are magnetic. Gold and silver have different electrical signals then rocks without gold and silver.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Step two is to go in the field and try to find the rocks. Then geologist would pick different types of soil, and rock samples. Then they would take the samples to the lavatory an analyze them. If they are a high amount of gold, silver, and zinc. Geologist would call that a good area.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   If the site looked promising then the next step is they would bring in a drill. And they would drill through the rock anywhere from 100 to 500 feet. Then a geologist would look at the rock samples from drilling and have them tested at a lab.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The educational requirements for a geologist are a minimum of a bachelor’s degree in geology. The average salary for a year is anywhere from 25,00 to 70,000.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Right now there are a lot of job opportunities for geologist in South America. That’s why I would choose to live and work in South America. The geography in South America is rugged mountain terrain. Some leisure activities are skiing,snowboarding, and mountain climbing. That’s why I think South America would be a great place to live for my type of job.

Positive Response Action

Positive Response Action: The ultimate goal of website communication Summary Understanding and knowing the audience is the key to delivering the message to them. The key to harnessing the Internet’s power is to understand all of the people with whom one will communicate with. Every website should have one overriding, generic entity goal to achieve positive response action. Both content and usability can be viewed as as cognitive ? triggers? , gateways to self-gratification and consequent PRA.Every website may be classified into one of three sender motivation categories: individual, strategic stakeholder communication, non-strategic communication. Content of the article Knowing the audience is important in every field and the key to the success, for example in marketing and public relations if you want to sell your product you need to know your customers’ needs and wants, and PR specialists need to know the audience too if they want their message to be delivered in a cam paign or programme. And the key to a successful website is knowing the audence in the same way.If you know the audience you can deliver and present your message and information more efficiently and are more likely to achieve your goals. Positive response action should be the goal of a website otherwise there is no point of the site. Positive response action was defined by six website visitor positive outputs for example the time spent on the website which should tell if the visitor is satisfied but it could be also questioned, because maybe s/he is not satisfied and is spending longer time on the site because s/he can’ find the information s/he wanted.Examples from practice The objective of an individual’s website might simply be so s/he can say they have one: Many individuals and also companies have websites which are often half-finished and don’t contain a message and are just existing in the Internet. A website without a meaning could leave a wrong first impr ession of the company for example and leave the visitor unsatisfied. Graphics take often a massive amounts of memory: I have noticed that due to low-speed Internet many people find it irritating to use the social networking siteMyspace, it takes a lot of time to load the graphics as I have experienced myself and also read from other users’ comments, and many have stopped using the site because of that. „Make sure your website is fast to access and is not slowed down by large images or fancy gadgets†(Chung) : „Myspace is set up so that anyone can customize the layout and colors of their profile page with virtually no restrictions. As Myspace users are usually not skilled web developers, this can cause further problems.Poorly constructed Myspace profiles could potentially freeze up web browsers due to malformed CSS coding, or as a result of users placing many high bandwidth objects such as videos, graphics, and Flash in their profiles (sometimes multiple video s and sound files are automatically played at the same time when a profile loads). †[i] Currently (March 2011) Myspace has an estimated 34 million users compared to Facebook’s 600 million for example, the reason for lower popularity might be the inability to satisfy the users and offer them satisfying experience.Myspace was also named the worst website by PC World in the list of 25 worst websites ever. Dimensions of Customer Value of Website Communication in Business-To-Business Relationships Summary During the last decade, websites have become widely accepted means of communication in business-to-business relationships and their use and importance is increasing constantly. At the same time, internet technologies advance rapidly, increasing customer expectations of website characteristics and possibilities, pressuring companies to actively further invest in their websites.Also to justify the website investments, companies have to design websites that fit to their custom ers’ need. For that they need to understand the value of websites for customers to enable companies to meet customer needs and expectations, direct resources efficiently, predict customer behaviour and achieve sustainable competitive advantage. The study portrays seven dimensions of CV of website communication in business-to-business relationships: convenience, efficiency, competence, confidence, comfort, appreciation and enjoyment. Content of the articleI agree that the qualitative methods are the most suitable for uncovering customer value dimensions as they are more in-depth and provide a more rich description conversely to the quantitative methods which involve more statistical data. It is important to fulfill the customer desired end-states that the study brought out if you want to satisfy your consumers, such as convenience and efficiency because people like to get things easily without spending very much time, nowadays in the Internet age especially people are used to getting things fast and the one who offers information or products most conveniently gets the clients and profit.Also appreciation is an interesting point that was brought out because people like little details and like to get gifts, it could play an influential role in keeping the customers or winning them to your side. Although dimensions brought up in the article was limited to the customers in the study and don’t represent all the industries and customers, these dimensions generalize the dimensions which could apply to other contexts too.However I think more research should be done in this area as the importance of website communication is increasing and companies need to know what their customers want as websites are also often the first impression of the company. Examples from practice Websites have become widely accepted means of communication in business-to-business relationships: Time is money and the Internet offers the possibility to reach to the businesses more qu ickly and also find them more quickly as businesses also do their research online. ———————– [i] Retrieved from: http://en. wikipedia. org/wiki/Myspace#Accessibility_and_reliability
