... When the electrons in a monatomic gas are excited, they jump to higher energy levels. As the electrons fall back down, and leave the excited state, energy is re-emitted in the form of em radiation, the wavelength of which refers to the discrete lines of the emission spectrum. Each element has its ow ...
