Neon is a noble gas and the second lightest member of group 18. It is monatomic, colorless, and chemically very inert under ordinary conditions because its outer electron shell is closed. In the atmosphere it is present only as a minor constituent, but it is readily recognized by the intense reddish-orange light emitted in low-pressure electrical discharges. Its technological importance rests mainly on this optical behavior and on its cryogenic properties.
Colourless gaseous element of group 18 on the periodic table (noble gases). Neon occurs in the atmosphere, and comprises 0.0018% of the volume of the atmosphere. It has a distinct reddish glow when used in discharge tubes and neon based lamps. It forms almost no chemical compounds. Neon was discovered in 1898 by Sir William Ramsey and M.W. Travers.
The name derives from the Greek neos for "new". It was discovered from its bright orange spectral lines by the Scottish chemist William Ramsay and the English chemist Morris William Travers in 1898 from a liquefied air sample.
Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of the element krypton in 1898. Like krypton, neon was discovered through the study of liquefied air. Although neon is the fourth most abundant element in the universe, only 0.0018% of the earth's atmosphere is neon.
From the Greek word neos, new. Discovered by Ramsay and Travers in 1898. Neon is a rare gaseous element present in the atmosphere to the extent of 1 part in 65,000 of air. It is obtained by liquefaction of air and separated from the other gases by fractional distillation.
Pure neon is a colorless, odorless, monatomic gas at ordinary temperature and pressure. When cooled below its boiling point it becomes a colorless cryogenic liquid, and at still lower temperature a solid. In a discharge tube it emits a bright red-orange glow from atomic emission lines.
Neon is best known for luminous advertising signs, indicator lamps, and decorative discharge tubes, where low-pressure neon gives a distinctive red-orange emission. Other gases or phosphors are used for many colors often called “neon” in commerce. Neon is also used in some high-voltage indicators, gas lasers such as helium-neon lasers, and specialized cryogenic applications. Liquid neon has a high refrigeration capacity per unit volume, but its cost limits broad use.
The largest use for neon gas is in advertising signs. 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 fluorine.
Although neon advertising signs account for the bulk of its use, neon also functions in high-voltage indicators, lightning arrestors, wave meter tubes, and TV tubes. Neon and helium are used in making gas lasers. Liquid neon is now commercially available and is finding important application as an economical cryogenic refrigerant.
Isotopes in Earth/Planetary Science
Neon is subject to stable isotopic fractionation by physical processes, such as exchange between gas, liquid, and solid phases. Small variations in the isotope-amount ratio n(22Ne)/n(20Ne) have been used to examine gas-liquid exchange processes during groundwater recharge (water moving downward from the surface) and discharge [29] M. Ozima, F. A. Podosek.

Holocher, M. S. Brennwald, R. Kipfer. Geochim. Cosmochim. Acta.67, 587 (2003)..
Isotopes in Geochronology
Some 21Ne and 22Ne form naturally in the Earth’s crust largely by reactions of 18O and 19F in minerals with neutrons and alpha particles emitted from uranium and thorium decay, called nucleogenic neon isotopes [29] M. Ozima, F. A. Podosek. Noble Gas Geochemistry: 2nd Edition, p. 286, Cambridge University Press, Cambridge, UK (2002)., [101] Noble Gases in Geochemistry and Cosmochemistry: Reviews in Mineralogy and Geochemistry, D. Porcelli, C. J. Ballentine, and R. Wieler (Eds.), p. 844, Mineralogical Society of America and the Geochemical Society, Washington, DC (2002).. In addition, neon isotopes can form at the surface of the Earth and in extraterrestrial bodies by cosmic-ray-induced spallation reactions on magnesium, silicon, aluminum, and sodium [103] T. E. Cerling, H. Craig. Annu. Rev. Earth Planet. Sci.22, 273 (1994)., [104] D. Lal, B. Peters. “Cosmic ray produced radioactivity on the earth”, in Cosmic Rays II, K. Sitte (Ed.), Springer-Verlag, New York (1967).. Analyses of all three stable neon isotopes may be used to distinguish these sources from primordial neon. The relative amounts of atmospheric neon and crustal nucleogenic neon isotopes in deep groundwaters and natural gases have been used in studies of solid-water-gas interactions and migration (Fig. IUPAC.10.1). The cosmogenic component is mainly detected in 21Ne and can be used to determine cosmic-ray exposure ages of rock samples, including meteorites exposed during travel through space and boulders exposed by melting of glacial ice (Fig. IUPAC.10.1).
Isotopes in Industry
Masers (Microwave Amplification by Stimulated Emission of Radiation) containing 20Ne have been used to study quantum physics. 21Ne may also play a role in maser studies of quantum physics [106] W. R. Bennett. Phys. Rev.126, 580 (1962)..
Isotopes Used as a Source of Radioactive Isotope(s)
22Ne is used to produce the radioisotope 22Na via the reaction 22Ne (p, n) 22Na [107] R. Policroniades, E. Moreno, A. Varela, G. Murillo, A. Huerta, M. E. Ortiz, E. Chávez. Rev. Mex. Fis. S.54, 46 (2008).. 20Ne has been used to produce the radioisotope 18F via the reaction 20Ne (d, 4He) 18F [107] R. Policroniades, E. Moreno, A. Varela, G. Murillo, A. Huerta, M. E. Ortiz, E. Chávez. Rev. Mex. Fis. S.54, 46 (2008)..
Neon has no stable neutral compounds known under ordinary chemical conditions. Its very high ionization energy and negligible electron affinity make conventional oxidation states chemically inaccessible. Laboratory studies have identified transient ionic or weakly bound species such as NeH⁺ and van der Waals complexes at low temperature or in plasmas, but these are not isolable bulk compounds. Neon clathrate hydrates have been reported only under suitable low-temperature, high-pressure conditions, where neon is physically trapped rather than chemically bonded.
Neon is a very inert element, however, it has been reported to form a compound with fluorine. It is still questionable if true compounds of neon exist, but evidence is mounting in favor of their existence. The ions, Ne+, (NeAr)+, (NeH)+, and (HeNe+) are known from optical and mass spectrometric studies. Neon also forms an unstable hydrate.
See more information at the Neon compound page.
Neon is not toxic and is not chemically reactive in normal use. The main hazards are physical: compressed gas cylinders can rupture if mishandled, and released gas can displace oxygen in confined spaces. Liquid neon and cold equipment can cause cryogenic burns and embrittle some materials. Discharge devices also involve electrical hazards and, in some cases, fragile glass under reduced pressure.
Atmospheric neon is chemically persistent and does not participate significantly in biological or geochemical reactions. It enters the air mainly from primordial atmospheric inventory and minor natural releases from rocks and waters; it is lost only slowly by atmospheric escape processes. Because it is inert, dilute, and nonbioaccumulative, neon has no known essential biological role and little direct ecological activity.
Commercial neon is obtained by fractional distillation of liquefied air, usually as a minor by-product of large oxygen and nitrogen production. Its low atmospheric abundance makes recovery more specialized than for argon, and purification requires separation from helium, hydrogen, and other light gases. Demand is concentrated in signage, electronics, lasers, and niche cryogenic uses. Recycling is possible from closed systems but is uncommon for small lamps and signs, so supply depends strongly on industrial gas infrastructure.
Obtained from production of liquid air as a byproduct of producing liquid oxygen and nitrogen.
Neon is a cosmically abundant light noble gas made chiefly during stellar nucleosynthesis in massive stars, especially through carbon and oxygen burning stages. It is found in the Sun, stellar atmospheres, nebulae, and planetary atmospheres, although its abundance in rocky planets is reduced by volatility and atmospheric loss. Several stable isotopes occur naturally, with ²⁰Ne dominant on Earth.
- The familiar red-orange sign color is produced by neon itself, not by a coating.
- Many commercial “neon” signs of other colors contain argon, mercury vapor, or phosphors instead.
- Neon was discovered through the fractional distillation of liquid air.
- Liquid neon is denser than liquid helium but boils at a much higher temperature.
- Neon has no known stable neutral compound at ambient conditions.
- The name comes from a Greek word meaning “new.”
