Interesting Facts about Neon

Interesting Facts about NeonWhile experimenting on liquid air, Sir William Ramsay and Morris Travers found neon in 1898.

Trace amounts of neon are located in the Earth's atmosphere.

Neon is remaining, along with xenon and krypton, when oxygen, nitrogen, carbon dioxide and argon are eliminated from air.

It can be produced commercially as the byproduct of liquefaction of air.

The concentration of neon in the atmosphere is approximately 1 part in 55,000 or 18.2 ppm by volume or 1 part in 79,000 of air by mass.

Neon is the 2nd lightest inert gas, as well as being the 2nd lightest noble gas following helium.

Neon is approximately two-thirds as dense as air.

It has three stable isotopes. 

Chemical Properties of Neon

Neon is chemically inactive. Up to now, it has been not possible to make neon react with some other compound or element.

Occurrence in nature and Extraction

The abundance of neon in regular air is 18.2 parts per million (0.0182 percent).


3 isotopes of neon can be found, neon-20, neon-21 and neon-22. Isotopes are several forms of an element. Isotopes vary from one another based on their mass number. The number written to the right of the element's name is actually the mass number. The mass number symbolizes the number of neutrons and protons in the nucleus of an atom of the element. The number of protons determines the element, however the number of neutrons within the atom of any one element can differ. Each variation is an isotope. 

Neon Facts for Kids

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.

Georges Claude began creating neon lighting in 1902, as he had surplus neon leftover as a by product of his air liquefaction company.

Neon is the fifth most abundant chemical element in the universe, following behind hydrogen, helium, oxygen, and carbon.

Neon has over forty times the refrigerating ability of liquid helium and three times that of liquid hydrogen.

Neon's rarity makes it fairly expensive, making liquid neon about 55 times more expensive than liquid helium.

Its mass abundance in the universe is about one part per 750.

While neon glows reddish orange in commercial signage, other noble gases create the other colors for neon signs.
