Krypton!
Krypton Kr 36
ATOMIC MASS 83.798
STATE Gas
DISCOVERY 1898 (Sir William Ramsay and Morris Travers)
This element’s name comes from the Greek word “kryptos”, which means the “hidden one”.
Krypton is naturally present in the air, but it is 20 times less abundant than neon.
Krypton is not found in any minerals and only tiny amounts of it can be found in the air.
Sir William Ramsey won a Nobel Prize in Chemistry for discovering the noble gases.
Pure krypton in a glass sphere: Krypton is a transparent gas but it glows with a blue-white light when electricity flows through it.
LIGHTING: Krypton is used in flash lamps used for high speed photography, and also in so-called neon lights.
Digital camera When this camera’s flash activates, it’s a result of krypton being electrified by the camera’s battery.
METRE: Between 1960 and 1983, the metre was defined with reference to light emitted by the krypton-86 isotope.
NUCLEAR: Radioactive krypton-85, made during nuclear fuel reprocessing, helps detect covert nuclear facilities.
Incandescent bulb This energy efficient Bulb contains krypton.
Plasma ball This globe contains a mixture of noble gases, including krypton.
Laser lighting Krypton can react with the element fluorine to form the compound krypton fluoride, which is used to power some kinds of laser.
