Determine the Name from the Chemical Formula

1) Name the Cation

If more than one oxidation state is possible, evaluate the anion in order to determine the oxidation state.  Include this information as a roman numeral in parentheses following the name of the cation.

2) Name the Anion

If the anion is monoatomic change the ending of the name to "-ide".  If it is polyatomic, the name is not changed.
