Ionization potential is the minimum amount of energy needed to remove the outermost electron from the gaseous isolated atom. Its unit is eV/atom or kJ/mol. Successive ionization energy is the amount of energy needed to remove electron successively from a gaseous ion, it may be termed as `I.E._2, I.E._3`, .... The difference in the values of `I.E._1, I.E._2`, . helps to determine electronic configuration of the elements.

C. `S_((aq))^(2+) = R_((aq))^(2+)`
D. cannot be co-related
