Determine
(i) the oxidation number of the metal,
(ii) the number of d electrons,
(iii) the coordination number,
(iv) the charge of the complex ion, and
(v) the number and type of ligands for the coordination compound shown below.

A) i = +2; ii = 3 d electrons; iii = 5; iv = 1+; v = zero monodentate and four bidentate
B) i = +3; ii = 2 d electrons; iii = 6; iv = 1+; v = two monodentate and two bidentate
C) i = +2; ii = 3 d electrons; iii = 5; iv = 1+; v = two monodentate and one bidentate
D) i = +3; ii = 3 d electrons; iii = 6; iv = 1+; v = two monodentate and two bidentate
E) None of the above have all five answers correctly presented
