STANDARD Chemistry Magnetic Properties MCQ Question
Type: MCQ-numerical-Medium-Class 11
The magnetic moment of a divalent ion in aqueous solution with atomic number 25 is
A
5.9 B.M.
B
2.9 B.M.
C
6.9 B.M.
D
9.9 B.M.
Correct Answer
Option A
Detailed Explanation
The electronic configuration of ion (25) is 1s²2s²2p⁶3s²3p⁶3d⁵4s². The number of unpaired electrons (n) is 5. The magnetic moment μ = √(n(n+2)) B.M. = √(5(5+2)) = √35 = 5.9 B.M.
