An ionic compound.

#### Explanation:

Copper(II) acetate is an ionic compound made up of copper(II) cations, ${\text{Cu}}^{2 +}$, and acetate anions, ${\text{CH"_3"COO}}^{-}$.

Notice that the copper(II) cations have a $2 +$ charge and that the acetate anions have a $1 -$.

This tells you that in order to balance the overall positive charge coming from the cation, you need two acetate anions for every $1$ copper(II) cations.

The chemical formula for copper(II) acetate will thus be

"Cu"("CH"_3"COO")_2 -># copper(II) acetate
