The most abundant element in the universe. Tenth most abundant element in the earth's crust. Most hydrogen is used in the production of ammonia. Also used in balloons and in metal refining. Also used as fuel in rockets. Its two heavier isotopes are: deuterium (D) and tritium (T) used respectively for nuclear fission and fusion. Commercial quantities are produced by reacting superheated steam with methane or carbon. In lab work from reaction of metals with acid solutions or electrolysis. 6rdmpx39PRk Hydrogen
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. Din cuvântul grecesc neos, nou 1 1766 Henry Cavendish London, England From the Greek words "hydro" and "genes" meaning "water" and "generator"

Neon is not known to be toxic
In a vacuum discharge tube, neon glows reddish orange
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.
