An ionic compound.

Explanation:

Copper(II) acetate is an ionic compound made up of copper(II) cations, #"Cu"^(2+)#, and acetate anions, #"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
