Krypton Ionization Energy

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

Kr -> Kr¹⁺ = 1350.7 kJ/mol = 323.13 Kcal/mol
Kr¹⁺ -> Kr²⁺ = 2350 kJ/mol = 562.20 Kcal/mol
Kr²⁺ -> Kr³⁺ = 3565 kJ/mol = 852.87 Kcal/mol
Kr³⁺ -> Kr⁴⁺ = 5070 kJ/mol = 1212.92 Kcal/mol
Kr⁴⁺ -> Kr⁵⁺ = 6240 kJ/mol = 1492.82 Kcal/mol
Kr⁵⁺ -> Kr⁶⁺ = 7570 kJ/mol = 1811.00 Kcal/mol
Kr⁶⁺ -> Kr⁷⁺ = 10710 kJ/mol = 2562.20 Kcal/mol
Kr⁷⁺ -> Kr⁸⁺ = 12200 kJ/mol = 2918.66 Kcal/mol
Kr⁸⁺ -> Kr⁹⁺ = 22229 kJ/mol = 5317.94 Kcal/mol
Kr⁹⁺ -> Kr¹⁰⁺ = 28900 kJ/mol = 6913.88 Kcal/mol
