- A2.87 B.M.
- B3.87 B.M.
- C3.47 B.M.
- D3.57 B.M.
✓
Answer
- 3.87 B.M.
Explanation:
The magnetic moment is associated with its spin angular momentum and orbital angular momentum.
Spin only magnetic moment value of Cr3+. ion is 3d3
Hence, magnatic moment
$(\mu)=\sqrt{\text{n(n+2)}}\text{BM}$
$=\sqrt{3(3+2)}=\sqrt{15}$
$=3.87\text{BM}$
