5 Ionization energy Ionization energy ( IE ) is the energy required to completely remove 1 mole of electrons from 1 mole of gaseous atoms (or ions). The first ionization energy (IE 1 , also I 1 ) is the energy required to remove the outermost electrons from gaseous atoms: atom (g) ion + (g) + e E = IE 1 > 0 Successive ionization energies (IE 2 ,IE 3 , etc.) are required to remove additional electrons from ions. ion + (g) ion 2+ (g) + e ∆E = IE 2 > IE 1
