Neon (Ne) is a colourless, odourless, nonflammable, inert gas.
Commonly known as a fill gas for colourful neon signs in outdoor advertising displays, neon's other uses include glow lamps as visual indicator devices, voltage regulation, and as a component in laser gas mixtures.

Commonly known as a fill gas for colourful neon signs in outdoor advertising displays, neon's other uses include glow lamps as visual indicator devices, voltage regulation, and lasers. In combination with other rare gases, neon is finding increased application in special fluorescent lamps.
Neon is also used in spark chamber mixtures, useful in atomic particle research.
Liquid neon has properties unique amongst other low-temperature cryogenic fluids in that its latent heat of vaporisation is almost double that of helium and 20 times that of hydrogen. It also has the greatest gas-to-liquid ratio of the atmospheric gases, 1445:1, meaning one liquid litre will evolve 1,445 gas litres (at room temperature). The space program uses liquid neon as a coolant for ultra-sensitive infrared imaging and detection equipment.
