Directions: Follow these steps to complete the assignment.

Step 1. Identify an element from the periodic table and assume that role

Step 2. Research the element using books, internet, or other materials

Step 3. Create a presentation about yourself (the element) that tells all about this element, its characteristics and its uses.

 

Your presentation must contain the following:   Element symbol   Element Name   Atomic Number   Atomic Mass   Is it a solid, liquid or gas?   Is it a metal, nonmetal or metalloid?   Family Name or Rare Earth Element Series   Who discovered it?   When discovered?   How is it used?   Physical, chemical properties or unusual facts (must have 3)   Resources cited (minimum of 2)    

PLEASEEEEEE SOMEONE HELP 

IT WOULD MEAN A LOT PLEASEEEE IF YOU CAN
