Naming Ionic Compounds with Polyatomic Ions

Any ionic compound with more than 2 elements can be assumed to contain one or more polyatomic ions.

You can tell how many elements a compound has by counting the number of capital letters in the formula.

Any ionic compound with more than 2 elements can be assumed to contain one or more polyatomic ions. You can tell how many elements a compound has by counting the number of capital letters in the formula. For example: CuSO 4 has 3 capital letters, so it has 3 elements.

Any ionic compound with more than 2 elements can be assumed to contain one or more polyatomic ions. You can tell how many elements a compound has by counting the number of capital letters in the formula. For example: CuSO 4 has 3 capital letters, so it has 3 elements. Because CuSO 4 has more than 2 elements, It must contain a polyatomic ion.

Once we know that a compound contains one or more polyatomic ions, we just locate that ion, or those ions, on the ion table.

The name of a polyatomic ion is NOT CHANGED when it is added to the name of a compound.

For example:

NaClO is named sodium hypochlorite

For example: NaClO is named sodium hypochlorite KNO 3 is named potassium nitrate

For example: NaClO is named sodium hypochlorite KNO 3 is named potassium nitrate LiMnO 4 is named lithium permanganate
