Rules for Naming Ionic Rules for Naming Ionic CompoundsCompounds

Name the Name the cationcation first. It is the first. It is the same as the element name of the same as the element name of the metalmetal..

Name the Name the anionanion second, but change second, but change the ending of the anion to the ending of the anion to ––ideide. For . For polyatomic ions, you write the polyatomic ions, you write the name of the polyatomic ion.name of the polyatomic ion.
