History
(Gr. //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.

Isotopes
Natural neon is a mixture of three isotopes. Six other unstable isotopes are known.

Compounds
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.

Properties
In a vacuum discharge tube, neon glows reddish orange. It has over 40 times more refrigerating capacity per unit volume than liquid [|helium] and more than three times that of liquid [|hydrogen]. It is compact, inert, and is less expensive than helium when it meets refrigeration requirements. Of all the rare gases, the discharge of neon is the most intense at ordinary voltages and currents.

Uses
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. Neon has no effect on the environment.

Costs
Neon costs about $2.00/l.
