The excited electron then loses its energy as it travels down the Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light and fall back down to their original energy level.
The lines in an emission spectrum occur when the electron loses energy, and "falls back", from a higher energy state to a lower one emitting photons at different frequencies for different energy transitions.
For an isolated atom or molecule in a gas, excited states of electrons often don't have any easy way to lose energy except by electromagnetic radiation- the light of some frequency. A little of the energy can go into internal vibrations for a molecule.
