Neon was discovered through the study of liquefied air by British chemists Sir William Ramsay and Morris M. Travers. A very common element throughout the universe, only 0.0018% of the earth’s atmosphere is neon. When ionized in a glass tube, neon emits a red light. This effect accounts for neon’s largest use in advertising lighting. Neon is also used to make high voltage indicators and is combined with helium to make helium-neon lasers. Liquid neon is used as a cryogenic refrigerant. Neon is highly inert and forms no known compounds, although there is some evidence that it could form a compound with flourine.
