the unit is the amount of energy required for all of the atoms in a mole of substance to lose one electron each: molar ionization energy or enthalpy, expressed as kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).

All energy has the base unit of the Joule, however when dealing with energies that effect atoms, molecules and subatomic particles, it’s often more convenient to use the electron volt. This is the amount of kinetic energy picked up by an electron when accelerated through a 1 volt field, and is 1.6 x 10^-19 joules.
If you’re talking about electromagnetic ionizing radiation, you might sometimes see inverse centimeter ( cm^-1) as a unit of energy. It is about 2 x 10^-23 joules.
