Why does it take so much more energy to remove the third electron of magnesium has to be explained. Concept introduction: The removal of electron from the outer shell of an atom is depends on ionization energies and that atom tends occupy or donates to get inert gas electron configuration for its stability. For better understanding of this problem we must know that core shield shell and core closed shell. Core shield shell: In this type of shells, electrons are outside the shell and require low ionization energy to remove electron from the atom. Core closed shell: In this type of shells, electrons are inside the shell and requires high ionization energy to remove electron from the atom.
