Go to You were assigned a number in class. That number corresponds to the atomic number of the element you will research on the site. For example, if you were assigned #1 by me in class today, that means your element is atomic #1, Hydrogen. If you are #2, that is Helium, and so on.

You will make a mini poster for next class. On an 8.5 X 11 inch piece of blank paper (no lines), provide the following information:

On the mini poster, show:
the element name,
atomic number,
atomic mass,
whether it is a metal or non-metal,
its period (horizontal row on the periodic table)
its group(family) (vertical column on the periodic table),
whether it is a solid, liquid, or gas at standard temperature and pressure (STP),
some of its characteristics,
interesting facts,
and applications/uses (what do we use that element for?)
Include at least one image.

Please be sure to include references on the mini poster (list all sources that you used).
