Correct answer
AMg2+<Na+<F-<O2-<N3-

Step-by-step explanation

These are all isoelectronic species. More the negative charge on the species, more is the size of that ion and more the positive charge on the species, less is the size of that ion.

The correct order of ionic radii isN-3>O-2>F->Na+>Mg+2Radii
