Rules for Writing Ionic Rules for Writing Ionic FormulasFormulas
The The cationcation comes first in the chemical comes first in the chemical formula for ionic compounds.formula for ionic compounds.
The The anionanion is written second in the is written second in the chemical formula for ionic compounds.chemical formula for ionic compounds.
Write the Write the symbolsymbol and the and the chargecharge of the of the cation next to the cation next to the symbolsymbol and and chargecharge of the anion.of the anion.
DropDrop the charges down and the charges down and swapswap them with the other symbol.them with the other symbol.

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.
