Binary means two different elements Ionic means metal and nonmetal Step 1 First give the name of the metal, followed by the nonmetal name using the “ide” suffix. Step 2 If the metal is to the right of group IIA, then a Roman numeral is used after the metal to to describe the charge of the metal. Except Ag, Zn,and Al Examples NaCl Al 2 O 3 FeCl 2 FeCl 3 NOMENCLATURE I. Binary Ionic compounds
