Na^+ Mg^2+ S^2- Cl^- thank you Click to expand... I think its: Mg^2+<Na^+<Cl^-<S^2- losing electrons means the protons are being pulled in tighter, due to z effective; while gaining electrons decreases the attractiveness of each electron to a proton. So the greater the positive charge, the smaller the nucleus Upvote 0 Downvote
