# What does "polarity" describe?

$\text{Polarity}$ describes separation of charge..........
However, in an ionic compound, charge separation has gone to the extreme, and we have DISCRETE CHARGED IONS. Thus polarity tends to describe polar, covalent bonds in molecular compounds such as $\stackrel{\delta +}{H} - \stackrel{\delta -}{F}$, ${\stackrel{\delta +}{H}}_{2} \stackrel{\delta -}{O}$, ${\stackrel{\delta +}{H}}_{3} \stackrel{\delta -}{N}$,
