A) zero
B) 1.83
C) 2.83
D) 1.73
Correct Answer: D
Solution :
Electronic configuration of \[\operatorname{Ce} = \left[ Xe \right]4{{f}^{2}}5{{d}^{0}}6{{s}^{2}}\] Electronic configuration of \[C{{e}^{3+}}=[Xe]\,4{{f}^{1\,}}5{{d}^{0}}\,6{{s}^{0}}\,i.e.,\,\,n=1\] \[\mu =\sqrt{n\left( n+2 \right)}=\sqrt{1\left( 1+2 \right)}=\sqrt{3}=1.73\]
