The magnetic nature of elements depends on the presence of unpaired electrons. Identify the configuration of transition element, which shows highest magnetic moment.

Options

A. `3d^(7)`
B. `3d^(5)`
C. `3d^(8)`
D. `3d^(2)`

Answer

B

Explanation

Greater the number of unpaired electron, higher will be its value of magnetic moment. Since, `3d^(5)` has 5 unpaired electrons hence highest magnetic moment.
`" "mu = sqrt(5(5+2))`
`" "sqrt(35)`
`" "=5.95 BM`
