Webthe 2nd ionisation of sodium. Na+ (g) → Na2+ (g) + e- The 2nd ionisation is always higher than the 1st, and the 3rd will be higher than the 2nd and so on. This is because after the 1st ionisation, you are trying to remove an electron from a positive ion, which will attract the outer electron more and make it more difficult to remove.
