Calculate the magnetic moment expected for a compound containing a first-row transition metal with three unpaired electrons.

Question

Quizplus · Accepted Answer

The magnetic moment of a compound can be calculated using the formula:
μ = √(n(n+2))BM
where n is the number of unpaired electrons and BM is the Bohr magneton (9.27 x 10^-24 J/T).
For a first-row transition metal with three unpaired electrons, n = 3.
Substituting this value in the above formula, we get:
μ = √(3(3+2))BM = √15BM = 3.87 μB
Therefore, the best choice is B with the explanation provided above.
