Expert Answer:

Atomic radius decreases across the period, however, neon being an inert gas experiences more repulsion between the different shells of electrons, thus the size of neon become greater than fluorine.

 

The size of sodium is greater than magnesium because when we move from left to right in a period the nuclear charge increases and thus nucleus pull the electron very strongly towards itself.Due to this atomic size decreases.
