*The is a periodic table for students by students. If you hover your cursor over a term you will be presented with information.  For example check out: element Hydrogen, types of elements: nonmetal, metal, or metalloid.  If you would like to put information on this web page you can submit it to me and I will publish it. I will add your name to a list of who contributed to the web page.
