Neon Facts

Neon Facts
Neon (Ne) is a colorless, non-metallic, very inert gas with an atomic number of ten. This member of the noble gas classification glows reddish orange in a vacuum tube.
Interesting Neon Facts:
While experimenting on liquid air, Sir William Ramsay and Morris Travers discovered neon in 1898.
The scientists had only recently discovered krypton prior to their discovery of neon, and would discover xenon shortly afterwards.
Neon is left over, along with krypton and xenon, when nitrogen, oxygen, argon, and carbon dioxide are removed from air.
Trace amounts of neon are found in the Earth's atmosphere.
The concentration of neon in the atmosphere is about 1 part in 55,000, or 18.2 ppm by volume or 1 part in 79,000 of air by mass.
It can be created commercially as the byproduct of liquefaction of air.
Neon is about two-thirds as dense as air.
Neon is the second lightest inert gas, as well as being the second lightest noble gas after helium.
It has three stable isotopes.
Georges Claude began creating neon lighting in 1902, as he had surplus neon leftover as a by product of his air liquefaction company.
In 1910, Georges Claude attempted to create interior home lighting using neon lights in vacuum tubes, but homeowners did not accept the idea due to their color.
Neon has over forty times the refrigerating ability of liquid helium and three times that of liquid hydrogen.
Neon is the fifth most abundant chemical element in the universe, following behind hydrogen, helium, oxygen, and carbon.
Its mass abundance in the universe is about one part per 750.
Neon's rarity makes it fairly expensive, making liquid neon about 55 times more expensive than liquid helium.
While neon glows reddish orange in commercial signage, other noble gases create the other colors for neon signs.
