Street lamps that give off yellow light are filled with sodium atoms. When an electric current is passed through the lamp, it causes the sodium atoms to emit yellow light. Mercury is often used in fluorescent lamps, lithium is not typically used in street lamps, and chlorine does not emit visible light when excited.
