Which elements of group-$1$ and group-$2$ differ from the other elements of the same group?
(A) Lithium $(Li)$ and beryllium $(Be)$,the first elements of Group-$1$ and Group-$2$ respectively,exhibit properties that differ from those of the other members of their respective groups. This is due to their small size,high electronegativity,and high polarizing power. Lithium shows diagonal relationship similarities to magnesium $(Mg)$,and beryllium shows similarities to aluminium $(Al)$.
