Protactinium Ionization Energy

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

Ionization Energy

Pa -> Pa1+ = 568 kJ/mol = 135.89 Kcal/mol
