Neon is a rare, inert gas that emits a reddish orange glow when it conducts electricity. It was discovered in 1898 by British chemists William Ramsay and Morris Travers.
It is a noble gas that sits between helium and argon in the periodic table. It was discovered by heating liquefied air and collecting the gases that came off it when it boiled.
Unlike its lighter cousins helium and argon, neon does not form any compounds with other elements. However, scientists do believe that it could form a compound with fluorine, which is also a noble gas.
In a liquid form, neon is used as a cryogenic refrigerant. It has 40 times the cooling capacity of liquid helium and over three times that of liquid hydrogen.
High voltage indicators are another use for neon. These lights are designed to warn people when there’s a potential electrical problem that can cause injury or death.
Taillights on cars and motorcycles are also a major neon application. They offer a color-safety element and are long-lasting because they have glass tubing to prevent breakage from corrosion.
Fracking applications for neon are also common because it is able to detect leaks that can be difficult to see with other gas detectors. It also has a penetrative ability that cuts through smoke and fog.
As an inert and nontoxic gas, neon has a low boiling point, which makes it an excellent choice for fracking. It can be used to trace the path of leaking methane and other hazardous gases in oil and gas extraction sites.
