The highest magnetic moment is shown by the transition metal ion with the configuration

Question

The highest magnetic moment is shown by the transition metal ion with the configuration (A) 3d2 (B) 3d5 (C) 3d7 (D) 3d9

Tardigrade Admin · Accepted Answer

Magnetic moment = √ 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,3d5 has highest value of magnetic moment.

Q. The highest magnetic moment is shown by the transition metal ion with the configuration

$3 d^{2}$

$3 d^{5}$

$3 d^{7}$

$3 d^{9}$

Magnetic moment = $n (n + 2) BM$

where n is the number of unpaired electrons. Maximum the value of unpaired electron, greater the value of magnetic moment. So, $3 d^{5}$ has highest value of magnetic moment.
