Vedclass · Answer

(C) Group $13$ elements have a valence shell electronic configuration of $ns^2 np^1$. Due to the inert pair effect,the stability of the $+1$ oxidation state increases down the group $(Al While $B$ and $Al$ primarily show $+3$ oxidation state,$Ga, In,$ and $Tl$ exhibit both $+1$ and $+3$ oxidation states due to the increasing reluctance of the $ns^2$ electrons to participate in bonding.

Which elements of group $13$ possess both $+1$ and $+3$ oxidation state?
