Tin Ionization Energy

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

Sn -> Sn¹⁺ = 708.6 kJ/mol = 169.52 Kcal/mol
Sn¹⁺ -> Sn²⁺ = 1411.8 kJ/mol = 337.75 Kcal/mol
Sn²⁺ -> Sn³⁺ = 2943 kJ/mol = 704.07 Kcal/mol
Sn³⁺ -> Sn⁴⁺ = 3930.2 kJ/mol = 940.24 Kcal/mol
Sn⁴⁺ -> Sn⁵⁺ = 6974 kJ/mol = 1668.42 Kcal/mol
Sn⁵⁺ -> Sn⁶⁺ = 9900 kJ/mol = 2368.42 Kcal/mol
Sn⁶⁺ -> Sn⁷⁺ = 12200 kJ/mol = 2918.66 Kcal/mol
Sn⁷⁺ -> Sn⁸⁺ = 14600 kJ/mol = 3492.82 Kcal/mol
Sn⁸⁺ -> Sn⁹⁺ = 17000 kJ/mol = 4066.99 Kcal/mol
Sn⁹⁺ -> Sn¹⁰⁺ = 20600 kJ/mol = 4928.23 Kcal/mol
