NEET Chemistry Transition Elements MCQ Question
Type: MCQ-numerical-Easy-Class 12
Calculate the magnetic moment in Bohr magnetons (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 (μ) is calculated using the spin-only formula μ = √(n(n+2)). For 4 unpaired electrons, μ = √(4(4+2)) = √24 = 4.90 BM.
