____________________________
Size of neon is greater than the fluorine atom because neon has a stable configuration i.e, octet and hence have the maximum number of electrons which increases the inter - electronic repulsions within the atom . This leads to increase in size of neon atom (NOBLE GAS) .
Sodium(1st group) and magnesium(2nd group) lie in the 3th period . The atomic size decreases as we move from left to right across a period and hence , SODIUM has a greater atomic size than MAGNESIUM .

the atomic size depends on electrostatic force between the charged particles, and it depends on the charges on them.
so when they have very large charge, they
strongly attract each other if they are of opposite charges; and repel strongly if they are of same charges.
That's why size of neutral neon is larger than than electronegative fluorine.
and Sodium have larger size than magnesium due to 1 more electron (1 more negative charge) than sodium.
Hope you got help from it mark my answer as brainliest.
