Use Coulomb's law to estimate the average distance between the sodium nucleus and the 3s electron. These tables list values of molar ionization energies, measured in kJ⋅mol −1. The maximum ionization energy also decreases from the first to the last row in a given column, due to the increasing distance of the valence electron shell from the nucleus. > The value of the wavelength at the start of the continuum represents the ionization energy: the energy needed to remove a "3s" electron from a sodium atom (the red arrow in the diagram below). Ionization energy trends plotted against the atomic number, in units eV. Nov 26, 2021 · The ionization energy associated with removal of the first electron is most commonly used. X + → X 2+ + e −. A Sodium atom, for example Sodium. Comparing the two values, we can see that sodium’s second ionization energy is much higher than its first ionization energy. 14 eV/atom to ionize it while neon, the noble gas immediately preceding it in the periodic table, requires 2081 kJ/mol or 21. 28 eV.
