Solution

The correct options are
B $[A r] 4 s^{2}$
C $[N e] 3 s^{2}$
D $[K r] 4 d^{5} 5 s^{2}$
The electronic configurations of elements whose atomic radii are determined by taking half the internuclear distance between like atoms are
$[A r] 4 s^{2}$ , $[N e] 3 s^{2}$ and $[K r] 4 d^{5} 5 s^{2}$ . These are metals and the radius is called metallic radius.
