Question

The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spin only magnetic moment value of Cr3+ ion is (A) 2.87 B.M. (B) 3.87 B.M. (C) 3.47 B.M. (D) 3.57 B.M.

Cr(24): 3d54s1 Cr3+: 3d3 μ = √n(n+2)=√3(3+2) = √15 = 3.87 B.M.

Q. The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spin only magnetic moment value of $C r^{3 +}$ ion is

$2.87 B . M .$

$3.87 B . M .$

$3.47 B . M .$

$3.57 B . M .$

$C r (24) : 3 d^{5} 4 s^{1}$
$C r^{3 +} : 3 d^{3}$
$μ = n (n + 2) = 3 (3 + 2)$
$= 15 = 3.87 B . M .$
