Californium Ionization Energy

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

Cf -> Cf¹⁺ = 608 kJ/mol = 145.45 Kcal/mol
