Question

Toppr Admin · Accepted Answer

Correct option is A- -4-90 BM-Electronic configuration of the ion-Cr-2- -Rightarrow -Ar- 4s-0 3d-4-n-4-Spin only magnetic moment -Rightarrow -sqrt -n-n-2- - -sqrt -4 -times -4-2-4-9-160- BM-Option A is correct-

The calculated spin only magnetic moment of $$Cr^{2+}$$ ion is

Correct option is A. $$4.90 BM$$
Electronic configuration of the ion:

$$Cr^{2+} \Rightarrow [Ar] 4s^0 3d^4$$

$$n=4$$
Spin only magnetic moment $$\Rightarrow \sqrt {n(n+2)} = \sqrt {4 \times (4+2)}=4.9 BM$$
Option A is correct.
