Bromine Ionization Energy

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

Br -> Br¹⁺ = 1139.9 kJ/mol = 272.70 Kcal/mol
Br¹⁺ -> Br²⁺ = 2104 kJ/mol = 503.35 Kcal/mol
Br²⁺ -> Br³⁺ = 3500 kJ/mol = 837.32 Kcal/mol
Br³⁺ -> Br⁴⁺ = 4560 kJ/mol = 1090.91 Kcal/mol
Br⁴⁺ -> Br⁵⁺ = 5760 kJ/mol = 1377.99 Kcal/mol
Br⁵⁺ -> Br⁶⁺ = 8550 kJ/mol = 2045.45 Kcal/mol
Br⁶⁺ -> Br⁷⁺ = 9940 kJ/mol = 2377.99 Kcal/mol
Br⁷⁺ -> Br⁸⁺ = 18600 kJ/mol = 4449.76 Kcal/mol
Br⁸⁺ -> Br⁹⁺ = 23900 kJ/mol = 5717.70 Kcal/mol
Br⁹⁺ -> Br¹⁰⁺ = 28100 kJ/mol = 6722.49 Kcal/mol
