Gallium Ionization Energy

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

Ga -> Ga¹⁺ = 578.8 kJ/mol = 138.47 Kcal/mol
Ga¹⁺ -> Ga²⁺ = 1979 kJ/mol = 473.44 Kcal/mol
Ga²⁺ -> Ga³⁺ = 2963 kJ/mol = 708.85 Kcal/mol
Ga³⁺ -> Ga⁴⁺ = 6200 kJ/mol = 1483.25 Kcal/mol
Ga⁴⁺ -> Ga⁵⁺ = 8700 kJ/mol = 2081.34 Kcal/mol
Ga⁵⁺ -> Ga⁶⁺ = 11400 kJ/mol = 2727.27 Kcal/mol
Ga⁶⁺ -> Ga⁷⁺ = 14400 kJ/mol = 3444.98 Kcal/mol
Ga⁷⁺ -> Ga⁸⁺ = 17700 kJ/mol = 4234.45 Kcal/mol
Ga⁸⁺ -> Ga⁹⁺ = 22300 kJ/mol = 5334.93 Kcal/mol
Ga⁹⁺ -> Ga¹⁰⁺ = 26100 kJ/mol = 6244.02 Kcal/mol
