Platinum Ionization Energy

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

Pt -> Pt¹⁺ = 870 kJ/mol = 208.13 Kcal/mol
Pt¹⁺ -> Pt²⁺ = 1791 kJ/mol = 428.47 Kcal/mol
Pt²⁺ -> Pt³⁺ = 2800 kJ/mol = 669.86 Kcal/mol
Pt³⁺ -> Pt⁴⁺ = 3900 kJ/mol = 933.01 Kcal/mol
Pt⁴⁺ -> Pt⁵⁺ = 5300 kJ/mol = 1267.94 Kcal/mol
Pt⁵⁺ -> Pt⁶⁺ = 7200 kJ/mol = 1722.49 Kcal/mol
Pt⁶⁺ -> Pt⁷⁺ = 8900 kJ/mol = 2129.19 Kcal/mol
Pt⁷⁺ -> Pt⁸⁺ = 10500 kJ/mol = 2511.96 Kcal/mol
Pt⁸⁺ -> Pt⁹⁺ = 12300 kJ/mol = 2942.58 Kcal/mol
Pt⁹⁺ -> Pt¹⁰⁺ = 14100 kJ/mol = 3373.21 Kcal/mol
