A

V

B

Cr

C

Mn

D

all of them will have equal magnetic moment

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Electronic configuration of ultimate and penultimate shell in ground state of these elements is as follows :

Magnetic moment `m = sqrt(N(N + 2))` Bohr magneton where `N` is number of unpaired electrons, `m` will be highest for `Cr` having `6` unpaired electrons.
