(B) The chemical formula for ammonium diammine dioxalato cobaltate$(III)$ is $(NH_4)[Co(NH_3)_2(C_2O_4)_2]$.In this complex,the central metal ion is $Co^{3+}$.Primary valency corresponds to the oxidation state of the metal ion,which is $3$.Secondary valency corresponds to the coordination number of the metal ion.The ligands are $2$ $NH_3$ (monodentate) and $2$ $C_2O_4^{2-}$ (bidentate).Coordination number = $(2 	imes 1) + (2 	imes 2) = 2 + 4 = 6$.Thus,the primary valency is $3$ and the secondary valency is $6$.

Which are the primary valency and secondary valency of the transition metal ion in ammonium diammine dioxalato cobaltate$(III)$ respectively?
