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

Options

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

Answer

D

Explanation

`"Magnetic moment" = sqrt(n(n+2))`
where, n = number of unpaired electrons Thus, higher the number of unpaired electrons, higher will be the magnetic moment. So, `3d^(5)` configuration will have highest magnetic moment.
