Historio
Neon was discovered in 1898 by the British chemists Sir William Ramsay and Morris W. Travers in London.

It was discovered when Ramsay chilled a sample of air until it became a liquid, then warmed the liquid and captured the gases as they boiled off.

After 1902, Georges Claude's company, Air Liquide, was producing industrial quantities of neon as a byproduct of his air liquefaction business.

Aplikoj
Neon is often used in brightly lit advertising signs.

It is also used in vacuum tubes, high-voltage indicators, lightning arrestors, wave meter tubes, television tubes, and helium-neon lasers.

Liquid neon is used as a cryogenic refrigerant.
Neon is not known to be toxic
