In , British chemists William Ramsay and Morris Travers discovered krypton as the residue of evaporating almost all of the other components of liquid air.

For his work in the discovery of several inert gases, Ramsay was awarded the Nobel Prize in Chemistry in Krypton has few practical applications, mostly in bright white light bulbs used in photography and in devices used in physical and chemical research.

Applications Krypton is used to fill electric lamp bulbs which are filled with a mixture of krypton and argon, and for various electronic devices. Krypton in the environment Krypton might be one of the rarest gases in the atmosphere, but in total there are more than 15 billion tonnes of this metal circulating in the planet, of which only about 8 tonnes a year are extracted, via liquid air.

Krypton difluoride is only stable below minus 22 degrees Fahrenheit minus 30 degrees Celsius , according to Chemicool. Because krypton is so rare and thus expensive , it has limited use.

The gas is injected into some incandescent lightbulbs, because it extends the life of the tungsten filament that makes those bulbs glow, according to Universal Industrial Gases Inc.

Because it is such a heavy gas, krypton is also sealed between the glass of some double-paned windows to help them trap heat. But even for this purpose, the noble gas argon is usually used because it is cheaper, according to Universal Industrial Gases.

The discovery of krypton occurred partially by accident. Scottish chemist William Ramsay and English chemist Morris Travers were extracting argon for air in hopes of evaporating it and finding a lighter chemical element to fill the gap in the Periodic Table between argon and helium. Inadvertently, however, the researchers overdid the evaporation, leaving only a heavy gas sample behind, according to Chemicool. Wondering if they might find something anyway, they analyzed the light spectrum of the gases in the sample and found something unknown — a brand-new element.

This new element was not lighter than argon, but heavier. The researchers dubbed this discovery "krypton," from the Greek word for "hidden," kryptos. See the full list of chemistry topics at the site map!
