Vedclass · Answer

(D) Atomic radius generally increases down a group due to the addition of a new electron shell. In the case of $N$ and $P$,both belong to Group $15$. $N$ is in the $2^{nd}$ period and $P$ is in the $3^{rd}$ period. Since $P$ is below $N$ in the group,the atomic radius of $P$ is larger than that of $N$. For other options: $Br$ ($4^{th}$ period) is larger than $Cl$ ($3^{rd}$ period). $Na$ ($1^{st}$ group) is larger than $Mg$ ($2^{nd}$ group) due to decreasing size across a period. $Sr$ ($5^{th}$ period) is larger than $Ca$ ($4^{th}$ period).

In which of the following pairs is the second atom larger than the first?
