Vedclass · Answer

(D) The correct answer is $(D)$.In the periodic table,as we move from left to right across a period,the atomic radius decreases due to an increase in effective nuclear charge.All the given elements ($Mg$,$Al$,$Si$,and $P$) belong to the $3^{rd}$ period.Their positions are: $Mg$ (Group $2$),$Al$ (Group $13$),$Si$ (Group $14$),and $P$ (Group $15$).Since $Mg$ is the leftmost element among these in the $3^{rd}$ period,it has the largest atomic radius.
