Cation Energies

The table gives the energies of the cations in their ground state configurations. The superscript in the state corresponds to the multiplicity. For example, the ground state of carbon is 3P, or a triplet state as shown in the diagram:
^ v^  ^     

The units are given in atomic units, that is Hartrees (H). One Hartree is 2625.5 kJ/mol. The energy reference is for totally dissociated atoms. In other words, the reference state is a gas consisting of nuclei and electrons all at infinite distance from each other.
