As you might expect, the third ionization energy is the energy needed to remove the third electron from an atom. It gets progressive more difficult to remove electrons and so we see that the first ionization energy is less than the second ionization energy, which is less than the third ionization energy, etc.

The third ionizaton enthalpy (3rd IE) of an element X is the energy required to remove one electron from each ion in a mole of gaseous X²⁺ ions producing one mole of gaseous X³⁺ ions.
i.e. X²⁺(g) → X³⁺(g) + e⁻ ...... ΔH = 3rd IE of X
i.e. X²⁺(g) → X³⁺(g) + e⁻ ...... ΔH = 3rd IE of X
