Listed below are the ionization energies for the first six ionizations of an imaginary element: 1st IE= 1,100 kJ/mol 2nd IE = 1,950 kJ/mol 3rd IE = 5,890 kJ/mol 4th IE = 6,740 kJ/mol 5th IE= 8,120 kJ/mol 6th IE= 9,050 kJ/mol Why is the 2nd ionization energy higher than the 1st ionization energy? Check the two that apply. The 2nd electron removed is a core electron and core electrons are closer to the nucleus and experience a higher effective nuclear charge. The attractive force between the 2nd electron and the nucleus is weaker and requires more energy to overcome than the attractive force between the 1st electron and the nucleus. The 2nd electron removed is a valence electron, but it is closer to the nucleus because the 1+ cation that it was removed from is smaller than the neutral atom. The attractive force between the 2nd electron and the nucleus is stronger and requires more energy to overcome than the attractive force between the 1st electron and the nucleus.
