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?

is there any interaction between alcohol and air in a closed system without any variance in temperature? is there any interaction between mothballs (napthalene) and air in the same conditions? by "interaction" i mean chemical reaction or phase change C2H5OH + O2 --> HC2H3O2 + H2O ??? this isn't reversible right?

what causes sublimation at low temperatures?

does anyone know of molecules that include both hydrophobic and hydrophilic groups, besides phospholipids?
