Calculate the spin only magentic moment ...

Calculate the spin only magentic moment of `M^(2+)` ion `(Z=27)`.

Text Solution

Verified by Experts

Electronic configuration of M atom with `Z = 27 ` is `[Ar] 3d^(7) 4s^(2)`
`:. `Electronic configuration of `M^(2+)` will be `[Ar] 3d^(7)` , i.e.,
Thus, it has three unpaired electrons.
`:. `Spin only magnetic moment `( mu) = sqrt(n( n+2))` B.M. `= sqrt(3(3+2)) = sqrt(15)` B.M. `= 3.87 `B.M.
