A very very small amount.
Yes, xenon is a rare and inert gas that occurs in trace amounts in Earth's atmosphere, at a concentration of about 0.000009%. It is produced by the radioactive decay of radon gas and is also released during volcanic activity.
Naturally xenon molecules contain a single atom. But the earliest xenon lasers used Xenon dimer Xe2.
They normally get xenon from fractional distillation of air.
Xenon is a trace gas. Air is about .08 parts per million of Xenon. (For every million grams of air, there are .08 grams of xenon)
Xenon is an element and, being an element, it cannot contain any compounds - man-made or natural.
Xenon has 54 electrons 77 neutrons and 54 electrons
Xenon is a noble gas. I would think any compounds would be hard to make with using Xenon.
Xenon is more than 4.5 times heavier than air.
It was discovered in liquefied air.
It is xenon
Approx 0.00001%.
From distillation of liquid air.
