Xenon Ionization Energy

The Xenon Ionization Energy is the energy required to remove from atom one mole of electrons with subsequent production of positively charged ion of Xenon.
Xe -> Xe⁺ + e^-
This process can be repeated many times, but the energy cost is increased dramatically. The general equation for the Xenon is:
Xe^N+ -> Xe^(N+1)+ + e^-

Xe -> Xe¹⁺ = 1170.4 kJ/mol = 280.00 Kcal/mol
Xe¹⁺ -> Xe²⁺ = 2046 kJ/mol = 489.47 Kcal/mol
Xe²⁺ -> Xe³⁺ = 3097 kJ/mol = 740.91 Kcal/mol
Xe³⁺ -> Xe⁴⁺ = 4300 kJ/mol = 1028.71 Kcal/mol
Xe⁴⁺ -> Xe⁵⁺ = 5500 kJ/mol = 1315.79 Kcal/mol
Xe⁵⁺ -> Xe⁶⁺ = 6600 kJ/mol = 1578.95 Kcal/mol
Xe⁶⁺ -> Xe⁷⁺ = 9300 kJ/mol = 2224.88 Kcal/mol
Xe⁷⁺ -> Xe⁸⁺ = 10600 kJ/mol = 2535.89 Kcal/mol
Xe⁸⁺ -> Xe⁹⁺ = 19800 kJ/mol = 4736.84 Kcal/mol
Xe⁹⁺ -> Xe¹⁰⁺ = 23000 kJ/mol = 5502.39 Kcal/mol
