First and second ionisation enthalpy

(B) The process $(i) X_{(g)} \to X^+_{(g)} + e^-$ represents the first ionisation enthalpy,which is the energy required to remove the first electron from a neutral gaseous atom.The process $(ii) X^+_{(g)} \to X^{2+}_{(g)} + e^-$ represents the second ionisation enthalpy,which is the energy required to remove the second electron from a unipositive gaseous ion.
