Question
Calculate spin only magnetic moment of divalent cation of transition metal with atomic number 25.
Advertisements
Solution
Electronic configuration of divalent metal ion.
M (25) = 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d5
M2+ = 1s2, 2s2, 2p6, 3s2, 3p6, 3d5
| ↑ | ↑ | ↑ | ↑ | ↑ |
Number of unpaired electrons = 5
Calculation of magnetic moment
∴ n = number of unpaired electrons
i.e., μ = `sqrt(n(n + 2))`
= `sqrt(5(5 + 2))`
= 5.92 BM.
