You use a cryogenics compressor--a machine that repeatedly compresses, cools and depressurizes air. As the air gets colder and colder, gases will drop out of it. At -191C you will get some krypton--the concentration in air is only one part per million, so you won't get much. (This is why krypton is very expensive.)
Krypton, symbol Kr, Atomic Number 36, is the element.
if super man had balls they would be made of krypton
It wasn't made - it's the debris from the planet Krypton.
It is a natural Noble gas.
Krypton was a planet, but when it exploded, the debris drifted into space and it contained radiation.
It can be made into Kryptonite which is highly effective at removing superhumans.
Krypton Tetrafluoride
The element krypton has the symbol Kr.
It is Krypton!
Krypton is a gas.
No, krypton is odorless.
Krypton is an element, and all elements are the result of nuclear fission, nuclear fusion or radioactive decay. Krypton is one of the byproducts of the nuclear fission of Uranium and Plutonium, either from atomic bombs or nuclear reactors. Since Krypton is not one of the results of a natural radioactive decay chain, the only other possible source of Krypton is from nuclear fusion, and the only source of fusion powerful enough to produce it would be a supernova.
