Vedclass · Answer

(C) Atomic radii generally decrease in a period from left to right due to an increase in the effective nuclear charge. In the second period,the elements are arranged as $Be (Z=4), B (Z=5), C (Z=6), N (Z=7)$. As we move from left to right,the effective nuclear charge increases,which pulls the valence electrons closer to the nucleus,resulting in a decrease in atomic size. Therefore,the correct order of atomic radii is $N < C < B < Be$.

The correct order of atomic radii of $B, Be, N$ and $C$ is
