Which of the following ion has the maximum magnetic moment?

Options

A. `Mn^(2+)`
B. `Fe^(2+)`
C. `Ti^(2+)`
D. `Cr^(2+)`

Answer

1

Explanation

(1) Valence shell electron configuration of `Mn^(2+)`is `3d^(5)`, therefore , has the maximum number of unpaired electrons equal to `5` and , therefore ,has maximum magnetic moment.
(2) Valence shell electron configuration of `Fe^(2+)` is `3d^(6)` , therefore, has the maximum number of unpaired electrons equal to `4`
Valence shell electron configuration of `Ti^(2+)` is `3d^(2)`, therefore , has the maximum number of unpaired electron equal to `2`
(4) Valence shell electron configuration of `Cr^(2+)` is `3d^(4)`, therefore, has the maximum number of unpaired electron equal to `4`
