Ununoctium Ionization Energy

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

There is no data about Ununoctium ionization energy
