NEET Chemistry Transition Elements MCQ Question with Solution

Calculate the magnetic moment (in Bohr Magneton, BM) for a transition metal ion with 4 unpaired electrons using the spin-only formula.

A

4.90 BM

B

5.92 BM

C

3.87 BM

D

2.83 BM

Correct Answer

Option A

Detailed Explanation

The magnetic moment is calculated using the spin-only formula: μ = √(n(n+2)), where n is the number of unpaired electrons. For n = 4, μ = √(4(4+2)) = √24 = 4.90 BM.
