#### Answer:

You mean single ions, e.g. $N {a}^{+}$? Yes, they are polar but they are not dipoles.

#### Explanation:

Single ions have charge, therefore by definition they are polar. However, there is no dipole. Dipole moment is a measure of the difference in charge between two ends of a covalent bond, as a function of the separation of the charge. A single ion is a point charge so dipolarity doesn't apply.
