Magnesium Ionization Energy

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

Mg -> Mg¹⁺ = 737.7 kJ/mol = 176.48 Kcal/mol
Mg¹⁺ -> Mg²⁺ = 1450.7 kJ/mol = 347.06 Kcal/mol
Mg²⁺ -> Mg³⁺ = 7732.6 kJ/mol = 1849.90 Kcal/mol
Mg³⁺ -> Mg⁴⁺ = 10540 kJ/mol = 2521.53 Kcal/mol
Mg⁴⁺ -> Mg⁵⁺ = 13630 kJ/mol = 3260.77 Kcal/mol
Mg⁵⁺ -> Mg⁶⁺ = 17995 kJ/mol = 4305.02 Kcal/mol
Mg⁶⁺ -> Mg⁷⁺ = 21703 kJ/mol = 5192.11 Kcal/mol
Mg⁷⁺ -> Mg⁸⁺ = 25656 kJ/mol = 6137.80 Kcal/mol
Mg⁸⁺ -> Mg⁹⁺ = 31642 kJ/mol = 7569.86 Kcal/mol
Mg⁹⁺ -> Mg¹⁰⁺ = 35461 kJ/mol = 8483.49 Kcal/mol
