Vedclass · Answer

(A) diagonal relationship exists between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table.These pairs are lithium $(Li)$ and magnesium $(Mg)$,beryllium $(Be)$ and aluminum $(Al)$,and boron $(B)$ and silicon $(Si)$.These similarities in properties are due to the similar polarizing power and similar ionic charge-to-size ratio of the diagonally adjacent elements.Therefore,lithium shows a diagonal relationship with magnesium $(X = Mg)$ and aluminum shows a diagonal relationship with beryllium $(Y = Be)$.

Lithium shows diagonal relationship with element $X$ and aluminum with $Y$. $X$ and $Y$ respectively are
