Further information: Ionization energy

Data are taken from the wavenumber compilation of Moore (1970) unless otherwise noted, and converted using the 2006 CODATA recommended values:

1 cm−1 = 0.000 124 137 3837(44) eV = 0.011 903 713 931(12) kJ mol−1
Z Element Ionization energy Ref.
(eV) (kJ mol−1)
1 Hydrogen 13.615 234 81(36) 1305.584 631(12)
2 Helium 24.617 7789(14) 2360.634 56(12)
