find the largest to smallest radius. F^+, Na^+, Mg^(2+), O^(2-). explain.

Answer 1

F⁺ is weird. It's probaly F^-

If it is F^-, they have given you isolectronic ions (They all have Neon configuration). The only variable that determines size for the series is the charge on the nucleus. Therefore, largest to smallest is O, F, Na, Mg ( for standard ions)

F+ is ridiculously small (less than O atom, let alone O^2-)
