					                                     An Element Research Poster              –       50 points

                                    (Answer ALL parts of each question completely!)

Choose an element on the periodic table (there’s a signup sheet so that no two people research the same element.)

Use the following websites or wikis to research your element:
        Webelements: http://www.webelements.com/
        Chemical Elements.com: http://www.chemicalelements.com/
        the Dynamic Periodic Table: http://www.ptable.com/
        Images of the Chemical Elements: http://images-of-elements.com/
        Wikipedia

Find out the following information about your element:
    1. What is it’s symbol?
    2. How did the symbol originate, if the symbol isn’t just an abbreviation of the element’s name? (From what
       language did it come, what did it mean in that language?)
    3. What is the element’s atomic number?
    4. What is the element’s atomic weight or molar mass?
                                                                                 o
    5. What state of matter is the element in at room temperature (20-25 C or 298K) Called the “standard state.”
    6. What period (horizontal row) is the element in?
    7. What group or family is the element in? If the group has a formal name (for example, the “halogens”), what does
       the group’s name mean?
    8. What block of the periodic table is the element in? (s, p, d, or f)
    9. Is the element a metal, semimetal, or nonmetal?
    10. Who discovered the element? When was it discovered? If the element has been known and used since ancient
        times, state that fact. What is the history of the element?
    11. Where is the element found (mined, produced, etc), and how is it produced (or isolated)?
    12. Are there particular compounds or ores that are important in its production? (For example, Al ore is mined as the
        mineral bauxite.)
    13. What are the uses of the element? Are there compounds of element that are important economically, in
        medicine, or in industry? (For example, a billion dollars worth of sulfuric acid is made each year. Most of it goes
        into fertilizers.)
    14. Is your element important in the environment, in geology, or in biology, especially the human body? Are there any
        hazards or risks associated with the element? (For example, cadmium can cause certain types of cancers.)
    15. Find an image of your element (or of one of its compounds or uses if no image of the element itself is available).


Place all the information above onto a small poster (NOT a full-sized posterboard). Use no more than half of a full-sized
posterboard.

Be absolutely sure that you do not “cut and paste” information from any websites, unless you cite the source of the
information correctly. “Cut and paste” without citation is plagiarism! Put all information into your own words.

DO be sure to cite the source of the image(s) that you place onto your poster.

Neatness, design, and artistic decoration DO count as 10 points of your overall grade.
                                          th
This project is due Wednesday, Sept. 29 , at the beginning of your class period. Late submissions (up to 1 day late) lose
10 points. I won’t accept any posters more than 1 day late.
