A small amount of neon in a partially evacuated glass tube emits a bright reddish-orange glow while conducting electricity. Neon is a rare gas present in the atmosphere to a very limited extent. It is obtained as a byproduct in the production of liquid air. The greatest commercial use of neon is in advertising signs (see lighting lighting, light produced by artificial means to allow visibility in enclosures and at night. For stage lighting, see scene design and stage lighting .

It is also used in high-intensity beacons, in some electron tubes, in Geiger counters, in automotive ignition timing lights, and in high-voltage warning indicators. It is used for particle detection in high-energy physics research. Neon finds use in lasers laser [acronym for light amplification by stimulated emission of radiation], device for the creation, amplification, and transmission of a narrow, intense beam of coherent light .

Liquid neon is a particularly good cryogenic refrigerant since it will absorb more heat without vaporizing than an equal volume of liquid helium or liquid hydrogen. Neon was discovered in 1898 by William Ramsay Ramsay, Sir William, 1852–1916, Scottish chemist. He was professor of chemistry at University College, Bristol (1880–87), and at University College, London (1887–1912).

neon

Chemical element, chemical symbol Ne, atomic number 10. One of the noble gases, neon is colourless, odourless, tasteless, and completely unreactive. It occurs in minute amounts in the atmosphere and is obtained by fractional distillation of liquefied air. When under low pressure, it glows a bright orange-red if an electric current is passed through it. It was discovered in 1898, and since the 1920s its chief use has been in luminous tubes and bulbs.
