Vedclass · Answer

(D) The electronic configuration of $C$ is $[Xe] \ 6s^2 \ 5d^1$,which corresponds to Lanthanum ($La$,$Z=57$).In the periodic table,$La$ is in Group $3$ and Period $6$.Since $A, B, C, E$ are in the same group (Group $3$),they represent the transition metals of Group $3$: $Sc$ $(Z=21)$,$Y$ $(Z=39)$,$La$ $(Z=57)$,and $Ac$ $(Z=89)$.Thus,$A=Sc$,$B=Y$,$C=La$,and $E=Ac$.Element $D$ is in the same period as $C$ but in the next group (Group $4$),which is Hafnium ($Hf$,$Z=72$).Comparing this with the given options:$A: La$ is incorrect (it should be $Sc$).$B: Sc$ is incorrect (it should be $Y$).$E: Hf$ is incorrect (it should be $Ac$).Therefore,all given options are incorrect.

Based on the provided image,identify the correct option for the elements $A, B, C, D, E$ given that $C$ has the electronic configuration $[Xe] \ 6s^2 \ 5d^1$.
