Most elements are not found on their own in nature. Typically they are found in compounds and must be refined in order to make a sample of the element. You have been hired by WebElements.com to expand their web site by adding full length articles on how elements are isolated. Each article has to pass by a committee of experts. Your job is: Select an element that does not usually appear on its own in nature. Research how this element is isolated. Questions to consider are: In what compound(s) is the element found? Describe the properties of this compound. What reactions are used to isolate the element on a large industrial scale? What about on a small scale in a laboratory? What other reactants are used? What are the other products? What steps in the process are physical rather than chemical changes? Explain why. Write balanced chemical equations (including states) for each step in the isolation process. Try to classify each reaction. For each reaction, discuss the conditions under which it must be done and possible hazards. For each reactant, discuss its hazards. For each product, discuss its uses, hazards, disposal, and so on. Discuss how hazards can be minimized. The final product will be an encyclopedia-type article. It must be well organized and easy to read, with no spelling or grammar errors. The information must be factual and unbiased, proper citations must be used, and a complete list of references must be provided. Note that a simple process that is completely described will not necessarily be as impressive to the committee as a more complex process that has some minor omissions.
