see this explanation:- The size of an isoelectronic species increases with a decrease in the nuclear charge (Z). For example, the order of the increasing nuclear charge of F– , Ne, and Na+ is as follows: F – < Ne < Na+ Z 9 10 11 Therefore, the order of the increasing size of F– , Ne and Na+ is as follows: Na+ < Ne < F–
