Why were you not asked to predict whether or not an ion is polar?

I believe ions (polyatomic or otherwise) would be neither polar nor nonpolar, but rather ionic. Polar and nonpolar are terms used to refer to molecules with an overall neutral charge, while ions are charged molecules or atoms. However, ions would BEHAVE LIKE polar molecules in the way that they are water soluble and lipid insoluble
