At standard temperature and pressure, pure xenon gas has a density of 5.894 kg/m 3, about 4.5 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3. [52] As a liquid, xenon has a density of up to 3.100 g/mL, with the density maximum occurring at the triple point. [53]
Xenon has a density of 5.894 × 10 −3 g/cm 3, liquifies at −161.4 °C, and solidifies at −165.051 °C. It is non- toxic , and belongs to a select group of substances that penetrate the blood–brain barrier , causing mild to full surgical anesthesia when inhaled in high concentrations with oxygen.

Xenon difluoride is a powerful fluorinating agent with the chemical formula XeF 2, and one of the most stable xenon compounds. Like most covalent inorganic fluorides it is moisture-sensitive. It decomposes on contact with water vapor, but is otherwise stable in storage. Xenon difluoride is a dense, colourless crystalline solid.
Xenon hexafluoride is a noble gas compound with the formula XeF 6. It is one of the three binary fluorides of xenon that have been studied experimentally, the other two being XeF 2 and XeF 4. All known are exergonic and stable at normal temperatures. XeF 6 is the strongest fluorinating agent of the series. It is a colorless solid that readily ...
A group of racial justice protesters reached a settlement with the federal government after filing a lawsuit accusing agents of using excessive force in 2020.
Xenon-135 (135 Xe) is an unstable isotope of xenon with a half-life of about 9.2 hours. 135 Xe is a fission product of uranium and it is the most powerful known neutron -absorbing nuclear poison (2 million barns ; [ 1 ] up to 3 million barns [ 1 ] under reactor conditions [ 2 ] ), with a significant effect on nuclear reactor operation.
