Titanium Ionization Energy

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

Ti -> Ti¹⁺ = 658 kJ/mol = 157.42 Kcal/mol
Ti¹⁺ -> Ti²⁺ = 1310 kJ/mol = 313.40 Kcal/mol
Ti²⁺ -> Ti³⁺ = 2652 kJ/mol = 634.45 Kcal/mol
Ti³⁺ -> Ti⁴⁺ = 4175 kJ/mol = 998.80 Kcal/mol
Ti⁴⁺ -> Ti⁵⁺ = 9573 kJ/mol = 2290.19 Kcal/mol
Ti⁵⁺ -> Ti⁶⁺ = 11516 kJ/mol = 2755.02 Kcal/mol
Ti⁶⁺ -> Ti⁷⁺ = 13590 kJ/mol = 3251.20 Kcal/mol
Ti⁷⁺ -> Ti⁸⁺ = 16260 kJ/mol = 3889.95 Kcal/mol
Ti⁸⁺ -> Ti⁹⁺ = 18640 kJ/mol = 4459.33 Kcal/mol
Ti⁹⁺ -> Ti¹⁰⁺ = 20830 kJ/mol = 4983.25 Kcal/mol
