Multivalance Roman numeral needed Identify the first element( check if it’s multi valence):identify the second element If the first element is multivalance you need to check which oxidation state will balance the charge on the second element and include it as a roman numeral CuCl 2 Copper is multivalance Cl has an oxidation state of-1 and there is two of them to balance this the one Cu must have an oxidation state of +2 Answer : copper(II) chloride

polyatomic

Formulas - given names Example Barium chloride Look for barium and chlorine on periodic table –determine their oxidation state Ba second column +2 Cl Seventh column -1 Ba +2 Cl -1 Criss-cross Answer: BaCl 2
