8.       Use two different symbols, one more than once, to create the chemical formula for water.

9.       Write a chemical equation for the formation of water.  Remember the left side of the arrow is the reactants and the right side is the products.

10.   The first column is known as the _________ metals and they _______ one electron because they are “givers”.

11.   The second column is known as the alkaline earth ___________ and they __________ electrons because they are “givers” also.

12.   The 18th column is known as the ________ gases, they are happy by themselves so they don’t ______ or ______ electrons.

13.   The Halogens are in column _____ and they are “takers” so they _____ one electron.
