Why does the paramagnetic nature of the 3d transition series increase till `Cr` and then decrease regularly?

Text Solution

Verified by Experts

From the electronic configuration of the 3d transition series, we can see that, as we go from left to right, the number of unpaired electrons increases from Sc to Cr and decreases thereafter. So the paramagnetic nature of the 3d transition series increaes till Cr and then decreases regularly.
