Out of `Mn^(3+)` & `Cr^(3+)`, which is more paramagnetic and why ? (Atomic nos : Mn = 25, Cr = 24)

Text Solution

Verified by Experts

`Mn^(3+):[Ar]3d^(4)4s^(0)` (4 unpaired electrons)
`Cr^(3+):[Ar]3d^(3) 4s^(0)` (3 unpaired electrons)
`Mn^(3+)` has more number of unpaired electrons than `Cr^(3+)`, thus it is more paramagnetic.
