Question

For a transition metal ion having seven electrons in its d-orbital the effective magnetic moment will be (A) 7.98 B.M. (B) 4.90 B.M. (C) 3.87 B.M. (D) 2.83 B.M.

If d-orbital contains 7-electrons, it has 3 unpaired electrons. ∴ μ = √n(n+2) = √3(3+2) = √3×5 = √15 = 3.87 B.M.

If d-orbital contains 7-electrons, it has 3 unpaired electrons.
$∴ μ = n (n + 2) = 3 (3 + 2) = 3 \times 5 = 15$
$= 3.87 B . M .$
