Zinc Ionization Energy

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

Zn -> Zn¹⁺ = 906.4 kJ/mol = 216.84 Kcal/mol
Zn¹⁺ -> Zn²⁺ = 1733.3 kJ/mol = 414.67 Kcal/mol
Zn²⁺ -> Zn³⁺ = 3832.6 kJ/mol = 916.89 Kcal/mol
Zn³⁺ -> Zn⁴⁺ = 5730 kJ/mol = 1370.81 Kcal/mol
Zn⁴⁺ -> Zn⁵⁺ = 7970 kJ/mol = 1906.70 Kcal/mol
Zn⁵⁺ -> Zn⁶⁺ = 10400 kJ/mol = 2488.04 Kcal/mol
Zn⁶⁺ -> Zn⁷⁺ = 12900 kJ/mol = 3086.12 Kcal/mol
Zn⁷⁺ -> Zn⁸⁺ = 16800 kJ/mol = 4019.14 Kcal/mol
Zn⁸⁺ -> Zn⁹⁺ = 19600 kJ/mol = 4689.00 Kcal/mol
Zn⁹⁺ -> Zn¹⁰⁺ = 23000 kJ/mol = 5502.39 Kcal/mol
