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

Tc -> Tc1+ = 702 kJ/mol = 167.94 Kcal/mol
Tc1+ -> Tc2+ = 1472 kJ/mol = 352.15 Kcal/mol
Tc2+ -> Tc3+ = 2850 kJ/mol = 681.82 Kcal/mol
Tc3+ -> Tc4+ = 4100 kJ/mol = 980.86 Kcal/mol
Tc4+ -> Tc5+ = 5700 kJ/mol = 1363.64 Kcal/mol
Tc5+ -> Tc6+ = 7300 kJ/mol = 1746.41 Kcal/mol
Tc6+ -> Tc7+ = 9100 kJ/mol = 2177.03 Kcal/mol
Tc7+ -> Tc8+ = 15600 kJ/mol = 3732.06 Kcal/mol
Tc8+ -> Tc9+ = 17800 kJ/mol = 4258.37 Kcal/mol
Tc9+ -> Tc10+ = 19900 kJ/mol = 4760.77 Kcal/mol
