Where Is Xenon Found in Nature?


Xenon is found in its natural form in the Earth's atmosphere, which contains about one part in 20 million of xenon gas. Xenon is a noble, or inert, gas that is odorless and colorless.

Sir William Ramsay and M.W. Travers discovered xenon in 1898. Its name comes from the Greek “xenos,” which means "strange." It is also a very heavy gas. Its chemical symbol is Xe, and it has an atomic number of 54. There are nine stable isotopes of this inert gas.

The method used to produce this gas commercially extracts it from liquid air. Its applications include bubble chambers, electron tubes and strong lamps that kill bacteria.
