Nobelium Ionization Energy

The Nobelium Ionization Energy is the energy required to remove from atom one mole of electrons with subsequent production of positively charged ion of Nobelium.
No -> No⁺ + e^-
This process can be repeated many times, but the energy cost is increased dramatically. The general equation for the Nobelium is:
No^N+ -> No^(N+1)+ + e^-

No -> No¹⁺ = 642 kJ/mol = 153.59 Kcal/mol
