One mole of particles given 1 eV of energy each has approximately 96.5 kJ of energy – this corresponds to the Faraday constant (F ≈ 96 485 C⋅mol −1), where the energy in joules of n moles of particles each with energy E eV is equal to E·F·n.
Values from CRC are ionization energies given in the unit eV; other values are molar ionization energies given in the unit kJ/mol.The first of these quantities is used in atomic physics, the second in chemistry, but both refer to the same basic property of the element.

These tables list values of molar ionization energies, measured in kJ⋅mol −1. This is the energy per mole necessary to remove electrons from gaseous atoms or atomic ions. The first molar ionization energy applies to the neutral atoms.
It is also an SI derived unit of molar thermodynamic energy defined as the energy equal to one joule in one mole of substance. [1] [2] For example, the Gibbs free energy of a compound in the area of thermochemistry is often quantified in units of kilojoules per mole (symbol: kJ·mol −1 or kJ/mol), with 1 kilojoule = 1000 joules.

The hartree (symbol: E h), also known as the Hartree energy, is the unit of energy in the atomic units system, named after the British physicist Douglas Hartree.Its CODATA recommended value is E h = 4.359 744 722 2060 (48) × 10 −18 J [1] = 27.211 386 245 981 (30) eV.
Boltzmann constant: The Boltzmann constant, k, is one of seven fixed constants defining the International System of Units, the SI, with k = 1.380 649 x 10 −23 J K −1. The Boltzmann constant is a proportionality constant between the quantities temperature (with unit kelvin) and energy (with unit joule). [3]
