Question

Which of the following ions has the maximum magnetic moment?

• A. $M{n}^{2+}$
• B. $F{e}^{2+}$
• C. $T{i}^{2+}$
• D. $C{r}^{2+}$

Answer 1

Answer: (A)

$M{n}^{2+}(3s^{2}3p^{6}3d^5)$ has the maximum number of impaired electrons $(5)$ and therefore $M{n}^{2+}$ has maximum magnetic moment.
