Xenon does not have any particular effect for two reasons:
Because Xenon is a gas and gases are found uncombined in nature, Xenon is found uncombined.ct
Xenon is an anaesthetic gas but otherwise is harmless.
It has no effect.
No, it is very rare.
Yes, it does.
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)
None of the isotopes of xenon ordinarily found in nature is radioactive. Like all elements, xenon has synthetic radioactive isotopes.
gas
In the atmosphere and, bonded with oxygen, in quartz.
It does not have any significant effect.
Xenon is a trace gas in Earth's atmosphere, occurring at 0.087±0.001 parts per million, or approximately 1 part per 11.5 million.
The particle nature of light is illustrated by the photoelectric effect.
