Vedclass · Answer

(A) Alkaline earth metals,such as $Barium$ $(Ba)$,belong to group $2$ of the periodic table and possess a stable electronic configuration of $ns^2$. They typically exhibit a fixed valency of $+2$ and do not show variable valency. In contrast,transition elements like $Titanium$ $(Ti)$ and $Copper$ $(Cu)$,as well as post-transition elements like $Lead$ $(Pb)$,exhibit variable valency due to the involvement of $d$ or $f$ electrons or inert pair effects.

Which of the following elements does not exhibit variable valency?
