The first ionization energy of the hydride ion is 0.7542 e V 0.7542 e V as calculated by Mills (Ref.1) and measured experimentally by Lykke, et al. (Ref.2).. This is much less than the well-known 13.6 e V 13.6 e V ionization energy of Hydrogen and follows the general rule that ionization energies increase as you remove more electrons.. In this case, the positive charge of the nucleus is ...
