Charge number

Charge number or valence of an ion is the coefficient that, when multiplied by the elementary charge, gives the ion's charge.

For example, the charge on a chloride ion, \mathrm{Cl}^-, is -1 \cdot e, where e is the elementary charge. This means that the charge number for the ion is -1.
