An ionic compound.
Copper(II) acetate is an ionic compound made up of copper(II) cations,
Notice that the copper(II) cations have a
This tells you that in order to balance the overall positive charge coming from the cation, you need two acetate anions for every
The chemical formula for copper(II) acetate will thus be
#"Cu"("CH"_3"COO")_2 ->#copper(II) acetate
