Discovery

(Gr. neos, new) Discovered by Ramsay and Travers in 1898. Neon is a rare gaseouselement present in the atmosphere to the extent of 1 part in 65,000 of air. It is obtainedby liquefaction of air and separated from the other gases by fractional distillation.

Sources

Neon is a rare gaseous element. It is present in the atmosphere to the extent of 1 part per 65,000 of air. Neon is obtained by liquefaction of air and separation using fractional distillation.

Uses

Neon is used to make neon signs. Neon and helium are used to make gas lasers. Neon is used in lightning arrestors, television tubes, high-voltage indicators, and wave meter tubes. Liquid neon is used as a cryogenic refrigerant, as it has over 40 times the refrigerating capacity per unit volume than liquid helium and over three times that of liquid hydrogen.
