Xenon Facts

Xenon Facts
Xenon (Xe) has an atomic number of fifty-four. It is an odorless, colorless, noble gas that gives off a blue glow when electrified in a vacuum tube.
Interesting Xenon Facts:
William Ramsay and Morris Travers discovered xenon in 1898.
Xenon was discovered shortly after they discovered krypton and neon.
Like krypton and neon, they discovered xenon by evaporating liquid air and studying the remains.
Xenon is a trace element in the Earth's atmosphere.
Ramsay believed xenon was only available in the atmosphere at about one part for every 20 million.
It is now known to be closer to one part per 11.5 million or about 0.087 parts per million.
Xenon is found in Mars' atmosphere at about 0.08 parts per million.
Jupiter has an exceptionally high amount of xenon, almost three times that of the Sun.
Under normal conditions, xenon has a surface density of around 4.5 times that of Earth's atmosphere.
Xenon can be forced into a solid metallic phase by extreme pressure, as much as several hundred kilobars.
In its metallic state, xenon has a sky blue color.
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.
The most stable of xenon's radioisotopes has a half-life of 2.11 sextillion years.
Several of xenon's unstable isotopes are produced from the fission of uranium and plutonium, and therefore result from a nuclear explosion.
Xenon has radioisotopes that are vital for nuclear reactors since they act as a neutron absorber, slowing the processes.
Xenon found in meteorites also serves as an indicator of solar system formation.
Due to electrical excitement, xenon is used in high-powered lamps and flash lamps such as photography strobe lights.
The first solid-state laser and the first excimer laser relied on xenon.
While inert and not readily reacting with other elements, xenon and oxygen compounds can be toxic and explosive.
