Ionic Compounds Containing Polyatomic Ions

Note: parentheses and a subscript are not used unless more than one of a polyatomic ion is present in the formula unit (e.g., the formula unit for calcium sulfate is "CaSO 4" not "Ca(SO 4)"). Rule 3. If the ion is a metal ion with a fixed charge, the name of the ion is the same as the (neutral) element from which it is derived (e.g., Na + = "sodium").
