$F$

Vedclass · Answer

(A) To determine the smallest size among $F, F^{-}, O$,and $N$:$1$. Comparing neutral atoms $(N, O, F)$: In the periodic table,atomic radius decreases from left to right across a period due to an increase in effective nuclear charge. Therefore,the order of size is $N > O > F$.$2$. Comparing an atom with its anion ($F$ vs $F^{-}$): An anion is always larger than its parent neutral atom because the addition of an electron increases inter-electronic repulsion,which causes the electron cloud to expand. Thus,$F $3$. Combining these observations,$F$ is smaller than $O, N$,and $F^{-}$.Therefore,$F$ has the smallest size.
