$[ Ne ] 3 s^2 3 p^5$

Vedclass · Answer

(A) The electronic configurations given in options $B$,$C$,and $D$ are $[ Ar ] 3 d^{10} 4 s^2$,$[ Kr ] 4 d^{10} 5 s^2$,and $[ Xe ] 4 f^{14} 5 d^{10} 6 s^2$ respectively. These configurations correspond to the general valence shell configuration of $(n-1)d^{10} ns^2$,which is characteristic of Group $12$ elements (Zinc,Cadmium,and Mercury). Option $A$ has the configuration $[ Ne ] 3 s^2 3 p^5$,which corresponds to Chlorine (Group $17$,Halogen family). Therefore,the element in option $A$ does not belong to the same family as the others.

Among the given configurations,identify the element which does not belong to the same family as the others?
