... Ionization Energy of Li2+ Ionization energy is the minimum energy required to just free an electron from its atom. So the final state of the electron should have zero total energy (i.e., K = U = 0.) Thus, the ionization energy is 0 – En = -En. Because an Li2+ ion has only one orbiting electron, it i ...
