WebThe first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. The reaction is represented for the generalized atom X as X→X^+ + e− The amount of energy required to remove an electron is related to the effective nuclear charge and the stability of the electron configuration of the atom. WebAboutTranscript. An element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay. Sort by:
