Question

Atomic radii of fluorine and neon in angstrom (A0) units are respectively given by

Answer 1

Atomic radii of fluorine and neon in angstrom units are respectively 0.42 and 0.38 amstrong. Atomic radius of fluorine is higher than neon because if we move from fluorine to neon one electron increases in the same valence shell. Hence the nuclear attraction towards valence shell increases.
