Chemistry Question on d -and f -Block Elements

Magnetic moment of Ce3+Ce^{3+} ion on the basis of ??pin-only?

A

1.2321.232

B

1.3321.332

C

1.5321.532

D

1.7321.732

Answer

1.7321.732

Explanation

Solution

The electronic configuration of Ce3+Ce^{3+} is 4f14f^1. Hence, μ=n(n+2)=1(1+2)\mu = \sqrt{n\left(n+2\right)}= \sqrt{1\left(1+2\right)} =1.732 B.M.= 1.732\,B.M.
