Q. The general electronic configuration of actinides is $( n -2)$ $f ^{ 1 -14}( n -1)\, d ^{0-1} \,ns ^{2} .$ Which one of the following actinides has one electron in $6 d$ -orbital?

The d-and f-Block Elements

Solution:

$Cm ( Z =96)$ have $[ Rn ] 5 f ^{7} \,6 d ^{1} \,7 s ^{2}$

$Lr( Z =103)$ have $[ Rn ] 5 f ^{14} \,6 d ^{1} \,7 s ^{2}$

$Np ( Z =93)$ have $[ Rn ] 5 f ^{4} \,6 d ^{1} \,7 s ^{2}$
