Cu(NO$_3$)$_2$
Cu$^{2+}$ = copper
NO$_3$$^{1-}$ = nitrate

Remember that you have:  $\sf \color{blue}{Metal}$$\sf \color{red}{(oxidation ~number)}$$\sf \color{violet}{Polyatomic~ion}$

And depending on the valance state it might be "cupric" [higher valence]
or "cuprous" [lower valence]

cupric and cupprous are more like common names. I don't think IUPAC uses those anymore tho.
