Potassium Ionization Energy

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

K -> K¹⁺ = 418.8 kJ/mol = 100.19 Kcal/mol
K¹⁺ -> K²⁺ = 3051.4 kJ/mol = 730.00 Kcal/mol
K²⁺ -> K³⁺ = 4411 kJ/mol = 1055.26 Kcal/mol
K³⁺ -> K⁴⁺ = 5877 kJ/mol = 1405.98 Kcal/mol
K⁴⁺ -> K⁵⁺ = 7975 kJ/mol = 1907.89 Kcal/mol
K⁵⁺ -> K⁶⁺ = 9649 kJ/mol = 2308.37 Kcal/mol
K⁶⁺ -> K⁷⁺ = 11343 kJ/mol = 2713.64 Kcal/mol
K⁷⁺ -> K⁸⁺ = 14942 kJ/mol = 3574.64 Kcal/mol
K⁸⁺ -> K⁹⁺ = 16964 kJ/mol = 4058.37 Kcal/mol
K⁹⁺ -> K¹⁰⁺ = 48575 kJ/mol = 11620.81 Kcal/mol
