Electron Binding Energies in Free Atoms

Work functions6 (WF); difference of binding energy in the outermost shell (ΔIP) and difference of binding energy in the next inner subshell (ΔBE) between Ref. 5 and Ref. 2; corrections (ΔK, ΔL₁, ΔL₂, etc.) applied to the values given in Ref. 2 in order to get binding energies for electrons in free atoms. All values are rounded to the nearest electron volt.

Binding energies (ionization energies) of electrons in free atoms in the ground state (in eV). The last digit is uncertain by 1–10 units (probable error), but in no case more than 2 eV.

Binding energies (ionization energies) of electrons in free atoms in the ground state (in electron volts). The last digit is uncertain by 1–10 units (probable error), but in no case up to 92 U more than 2 eV. If a digit is thought to be uncertain by more than 10 units (transuranium elements), it is printed in italics.

Ionization potentials of the He i sequence according to Pekeris.18 Digits that are different from those of Ref. 7 are printed in italics.
