The concept used is to identify the number of valence electrons present in the neutral atom of the certain element.
Ionization energy is the amount of energy required to remove an electron from the neutral isolated gaseous molecule.
The ionization energy for the removal of valence electrons is relatively lower than the ionization energy for the removal of core electrons.
