Vedclass · Answer

(D) The electronic configurations of the given elements are as follows:$A$. $Cd$ $(Z=48)$: $[Kr] 4d^{10} 5s^2$. It belongs to the $d$-block $(III)$.$B$. $Eu$ $(Z=63)$: $[Xe] 4f^7 6s^2$. It belongs to the $f$-block $(I)$.$C$. $Se$ $(Z=34)$: $[Ar] 3d^{10} 4s^2 4p^4$. It belongs to the $p$-block $(IV)$.$D$. $Ba$ $(Z=56)$: $[Xe] 6s^2$. It belongs to the $s$-block $(II)$.Therefore,the correct matching is $A-III, B-I, C-IV, D-II$.
