(1) $(c)CaCl_2$ (2) $(a) LiBr$ and $(b) NaNO_2$
Figure (1) represents a compound with 1 cation and 2 anions. The only formula with this configuration is $CaCl_2$. Cation: $Ca^{2+}$; Anion: $Cl^-$. Figure (2) represents a compound with equal amounts of anions and cations. This case only appears in $LiBr$ and $NaNO_2$, where both have only 1 of each ion in their formulas.
