We know that radius decreases when swe move from left to right in a period. Then why radius of neon is more than the radius of flourine?

Expert Answer:

The radii of noble gas elements are "van der Waals radii" and are 40% more than the actual atomic radii.

Hence neon's atomic radius must be much more than that of fluorine.
