Do you know what an Ionic Compound is?
Well as you may know; ion- a charged ion.
There are two different charges that consists with these Ions known as; Cation and Anion.

These charges play a large role in a method called "The Criss Cross Method."
You have your formula with charges included, then you must do the criss cross method to balance the formula.
Ex: Na+1 N-3
C.C.M. : Na3 N
See how you use the charges to balance the equations?
