The rules for ionic compounds are as follows:
1. The metal keeps its name and is named and written first.
– For transition metals, we use Roman numerals to denote its charge.
2. The nonmetal keeps its base name but has its ending changed to –ide.
– For polyatomic ions, name the polyatomic ion as you would normally.
