(A) The atomic radius of $F$ is measured as a covalent radius, whereas the atomic radius of $Ne$ is measured as a van der Waals' radius.By definition, the van der Waals' radius is always larger than the covalent radius for a given element.Therefore, the atomic radius of $F$ is smaller than the atomic radius of $Ne$ ($F = 72 \ pm$, $Ne = 160 \ pm$).The correct order is $F < Ne$.
