How would you explain the fact that the second ionisation potential is always higher than the first ionisation potential?

थोडक्यात उत्तर

Second ionization potential is always higher than the first ionization potential.
Removal of one electron from the valence orbit of a neutral gaseous atom is easy so first ionization energy is less. But from a uni positive ion, removal of one more electron becomes difficult due to the more forces of attraction between the excess of protons and less number of electrons.
Due to greater nuclear attraction, second ionization energy is higher than first ionization energy.
