Where is Xenon naturally found?
the atmosphere
Natural abundance Xenon is present in the atmosphere at a concentration of 0.086 parts per million by volume. It can also be found in the gases that evolve from certain mineral springs. It is obtained commercially by extraction from liquid air.

Is uranium on Mars?
Mars has uranium ore scattered on the surface, which the Martians could use to become self-sustained. Every 15 years, the 108 Kilopower reactors will need their uranium changed as the core gets depleted and looses power. Each reactor needs 226 kg of uranium core, or 24.4 tonnes of uranium to change all the reactors.
Why is xenon so important?
Xenon is used in certain specialised light sources. It produces a beautiful blue glow when excited by an electrical discharge. Xenon lamps have applications as high-speed electronic flash bulbs used by photographers, sunbed lamps and bactericidal lamps used in food preparation and processing.
How is xenon produced?
Xenon, from the Greek for ‘stranger’ is a colourless, odourless group 18 noble gas. Discovered in 1898 in London by William Ramsay, xenon is produced commercially by the fractional distillation of liquid air and is isolated as a by-product of the cryogenic production of oxygen and nitrogen.
How many isotopes does xenon have?
There are eight naturally occurring stable isotopes of xenon. This is more than any other element except for tin , which has ten stable isotopes. No other elements have more than seven stable isotopes. There are more than forty radioactive isotopes of xenon.
What does xenon radioisotopes mean?
Xenon Radioisotopes. Unstable isotopes of xenon that decay or disintegrate emitting radiation. Xe atoms with atomic weights 121-123, 125, 127, 133, 135, 137-145 are radioactive xenon isotopes.
Where is xenon found naturally?
Xenon is a trace gas found in the Earth’s atmosphere to the extent of about one part in 20 million, According to the Los Alamos National Laboratory . This makes it very rare. It is also found in Mars’ atmosphere at 0.08 ppm. This noble gas can also be found down on Earth.
What is the atomic structure of xenon?
Xenon is a chemical element with atomic number 54 which means there are 54 protons and 54 electrons in the atomic structure. The chemical symbol for Xenon is Xe. Xenon is a colorless, dense, odorless noble gas found in the Earth’s atmosphere in trace amounts.[10] Although generally unreactive, xenon can undergo a few chemical reactions.
