Vedclass · Answer

(B) In the periodic table of elements,gallium $(Ga)$ belongs to the boron family (group $13$).This group includes the elements boron $(B)$,aluminium $(Al)$,gallium $(Ga)$,indium $(In)$,and thallium $(Tl)$.Therefore,aluminium $(Al)$ belongs to the same family as gallium $(Ga)$.The electronic configuration of these elements shows they have $ns^2 np^1$ valence shell configuration.$Ga (Z=31) = [Ar] 3d^{10} 4s^2 4p^1$$Al (Z=13) = [Ne] 3s^2 3p^1$

Which element belongs to the family of elements that also includes the element gallium?
