Nov 21, 2010 · The ionization energy of an atom is the energy required to remove the electron completely from the atom.(transition from ground state n = 0 to infinity n = ∞). For hydrogen, the ionization energy = 13.6eV; When an excited electron returns to a lower level, it loses an exact amount of energy by emitting a photon. The Lyman(ultraviolet) series of spectral lines corresponds to electron transitions from higher energy levels to level n = 1.

Hydrogen molecules are first broken up into hydrogen atoms (hence the atomic hydrogen emission spectrum) and electrons are then promoted into higher energy levels. Suppose a particular electron was excited into the third energy level. This would tend to lose energy again by falling back down to a lower level. It could do this in two different ways.
