(a) Nuclear Charge (Z)

Because although all three elements have same number of electrons but inside nucleus the number of protons in unequal.In case of F- it is having only 9 proton and 10 electron so size will expand liitle.In case of Ne it has 10 proton and 10 electron but will have size smaller than F-.In case of Na+ it will have 11 proton and 10 electron, it means nucleus is more positive than available electrons in orbitals and hence there will be shrinking of size of Na+.

F-> Ne > Na+  Size order for these isoelectronic species.
