The 'spin only' magnetic moment is the same for which of the following ions?

A. \mathrm{Ti^{3+}} · B. \mathrm{Cr^{2+}} · C. \mathrm{Mn^{2+}} · D. \mathrm{Fe^{2+}} · E. \mathrm{Sc^{3+}}

D. Spin-only moment depends on unpaired electrons: \mathrm{Ti^{3+}} (d^1) 1, \mathrm{Cr^{2+}} (d^4) 4, \mathrm{Mn^{2+}} (d^5) 5, \mathrm{Fe^{2+}} (d^6) 4, \mathrm{Sc^{3+}} (d^0) 0. B and D both have 4 unpaired electrons, \mu = \sqrt{24} \approx 4.9 BM.
