Brief description |
| |
The melting point of neon is -248.67°C, boiling point is -246.048°C (1 atm), density of gas is 0.89990 g/l (1 atm, 0°C), density of liquid at b.p. is 1.207 g/cm3, and valence is 0. Neon is very inert, but it does form some compounds, such as with fluorine. The following ions are known: Ne+, (NeAr)+, (NeH)+, (HeNe)+. Neon is known to form an unstable hydrate. Neon plasma glows reddish orange. The discharge of neon is the most intense of the rare gases at ordinary currents and voltages.

Uses of Neon |
| |
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.
