Caesium Ionization Energy

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

Cs -> Cs¹⁺ = 375.7 kJ/mol = 89.88 Kcal/mol
Cs¹⁺ -> Cs²⁺ = 2420 kJ/mol = 578.95 Kcal/mol
Cs²⁺ -> Cs³⁺ = 3400 kJ/mol = 813.40 Kcal/mol
Cs³⁺ -> Cs⁴⁺ = 4400 kJ/mol = 1052.63 Kcal/mol
Cs⁴⁺ -> Cs⁵⁺ = 6000 kJ/mol = 1435.41 Kcal/mol
Cs⁵⁺ -> Cs⁶⁺ = 7100 kJ/mol = 1698.56 Kcal/mol
Cs⁶⁺ -> Cs⁷⁺ = 8300 kJ/mol = 1985.65 Kcal/mol
Cs⁷⁺ -> Cs⁸⁺ = 11300 kJ/mol = 2703.35 Kcal/mol
Cs⁸⁺ -> Cs⁹⁺ = 12700 kJ/mol = 3038.28 Kcal/mol
Cs⁹⁺ -> Cs¹⁰⁺ = 23700 kJ/mol = 5669.86 Kcal/mol
