Americium Ionization Energy

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

Am -> Am¹⁺ = 578.2 kJ/mol = 138.33 Kcal/mol
