Greater than the first ionization potential

Vedclass · Answer

(C) The second ionization potential is greater than the first ionization potential. After the removal of the first electron $(e^-)$,the remaining electrons are more strongly attracted by the nucleus due to an increase in the effective nuclear charge $(Z_{eff})$ and a decrease in electron-electron repulsion. Therefore,more energy is required to remove the second electron.
