ANSWER:Step 1 of 3
The successive ionisation energy of any element increases due to the increase in the nuclear charge towards the outermost electron. As the number of electron is removed from an atom, the positive charge on the atom increases, so that the interaction between the nucleus and outermost electron increases.
