Vedclass · Answer

(D) In the periodic table,atomic radii decrease from left to right across a period and increase from top to bottom down a group.$N$ and $F$ belong to period $2$,while $Al$ and $Si$ belong to period $3$.Since period $3$ elements have a larger principal quantum number $(n=3)$ than period $2$ elements $(n=2)$,$Al$ and $Si$ are larger than $N$ and $F$.Within period $3$,atomic radius decreases from left to right: $Al > Si$.Within period $2$,atomic radius decreases from left to right: $N > F$.Therefore,the correct order of atomic radii is $Al > Si > N > F$.

The correct order of atomic radii of $N$,$F$,$Al$,and $Si$ is:
