Q. The highest magnetic moment is shown by the transition metal ion with the configuration
A) $3d^{2}$
B) $3d^{5}$
C) $3d^{7}$
D) $3d^{9}$
Explanation
(b)
Magnetic moment =$\sqrt{n(n + 2)}\ BM$
Where, $n$ is the number of unpaired electrons. Maximum the value of unpaired electron, greater the value of magnetic moment. So, $3d^{5}$ has highest value of magnetic moment.
