what is the effect of ionization on atomic radii? i assume that an anion has a larger radius than a neutral atom and that a cation has a smaller radius. this would mean that the attractive force between the protons and electrons would increase when there are less electrons and decrease when their are more.
or does changing the balance in either way mean that the attraction is greater, regardless of whether there is increase in positive or negative charge, and thus that either type of ionization decreases atomic radius?
