The charge on the sodium ion, $N {a}^{+}$ is +1. The charge on the chloride $C {l}^{-}$ is -1.

#### Explanation:

The physical movement of an ion is caused by electrostatic attraction.

Thus, a $C {l}^{\text{-}}$ ion will move towards a positive charge, and an $N {a}^{\text{+}}$ ion will move towards a negative charge.
