##### Reference no: EM13565756

Ionization energy is defined as the amount of energy input that is needed from an outside source to remove an electron from an atom. Ionization, in the quantum view, corresponds to raising an electron to the n = 1 electronic state.

What is the ionization energy of a hydrogen atom which is in the ground (n = 1) state?
