Mendelevium Ionization Energy

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

Md -> Md¹⁺ = 635 kJ/mol = 151.91 Kcal/mol
