Naming Ionic Compounds
with Polyatomic
Ions
Any ionic compound with more than 2 elements can be assumed to contain one or more 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: CuSO4 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: CuSO4 has 3 capital letters, so it has 3 elements.Because CuSO4 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:
For example:NaClO is named sodium hypochlorite
For example:NaClO is named sodium hypochloriteKNO3 is named potassium nitrate
For example:NaClO is named sodium hypochloriteKNO3 is named potassium nitrateLiMnO4 is named lithium permanganate
