Vedclass · Answer

(B) Atomic radii increase as we move down the group due to the addition of an extra energy shell. Although the nuclear charge also increases,the effect of the addition of a new energy shell predominates. The increase in atomic radius is most significant when moving from $Na$ ($Z=11$,$3s^1$) to $K$ ($Z=19$,$4s^1$) because the transition from the $n=3$ shell to the $n=4$ shell involves a substantial increase in shielding and distance from the nucleus compared to subsequent transitions in the group. Therefore,the largest difference in radii is observed for the pair $Na, K$.
