A d-block element has total spin value of Then, the spin only magnetic moment of
A d-block element has total spin value of \( +3 . \) Then, the spin only magnetic moment of the element is approximately:
- A. 2.83 В.M.
- B. 3.87 В.М.
- C. 5.9 в.М
- D. 6.93 В.М.
Step-by-step solution
Total spin value of +3 implies the total spin quantum number S = 3/2 (since each unpaired electron contributes 1/2). Thus, number of unpaired electrons n = 2S = 3. Spin-only magnetic moment μ = √[n(n+2)] = √(3×5) = √15 ≈ 3.87 B.M.
