Xenon has diminutive cardinal 54; that is, its basis contains 54 protons. At accepted temperature and pressure, authentic xenon gas has a body of 5.761 kg/m3, about 4.5 times the apparent body of the Earth's atmosphere, 1.217 kg/m3.39 As a liquid, xenon has a body of up to 3.100 g/mL, with the body best occurring at the amateur point.40 Beneath the aforementioned conditions, the body of solid xenon, 3.640 g/cm3, is college than the boilerplate body of granite, 2.75 g/cm3.40 Using gigapascals of pressure, xenon has been affected into a brownish phase.41
Solid xenon changes from face-
centered cubic (fcc) to hexagonal abutting arranged (hcp) clear appearance beneath burden and begins to about-face brownish at about 140 GPa, with no apparent aggregate change in the hcp phase. It is absolutely brownish at 155 GPa. When metalized, xenon looks sky dejected because it absorbs red ablaze and transmits added arresting frequencies. Such behavior is abnormal for a metal and is explained by the almost baby widths of the electron bands in brownish xenon.4243
