A colorless, odorless factor within the noble fuel team occurring in particularly modest quantities inside the ambiance. It was the main noble gas uncovered to form compounds with other features. Xenon is used in lamps that make intense flashes, which include strobe lights and flashbulbs for photography.
: a heavy, colorless, and relatively inert gaseous component that occurs in air as about 1 element in 20 million by volume —symbol Xe
xenon - a colorless odorless inert gaseous component taking place during the earth's environment in trace quantities
This week we enter the stranger realms of chemistry as we listen to the Tale of xenon. He's Peter Wothers.

argonon, inert gas, noble gas - any of your chemically inert gaseous factors from the helium team during the periodic table
Various purple lines, three outstanding and equidistant, and several other blue traces were found. Is this pure krypton, in a tension which won't convey out the yellow and environmentally friendly, or a new fuel? In all probability the latter!' They noted that one of the most putting element of this new gasoline was The attractive blue glow in the discharge tube.
The pace of sound in xenon gas (169Â m/s) is under that in air[one hundred eighty] because the ordinary velocity from the heavy xenon atoms is lower than that of nitrogen and oxygen molecules in air. As a result, xenon vibrates a lot more gradually during the vocal cords when exhaled and creates decreased voice tones, an impact reverse towards the high-toned voice produced in helium. Like helium, xenon would not satisfy the human body's require for oxygen, and it truly is both equally a straightforward asphyxiant and an anesthetic much more highly effective than nitrous oxide; Therefore, and since xenon is expensive, lots of universities have prohibited the voice stunt for a typical chemistry demonstration.
When xenon atoms are in the ground energy state, they repel one another and will not likely kind a bond. When xenon atoms gets to be energized, nevertheless, they might type an excimer (psyched dimer) until finally the electrons return to the bottom state. This entity is shaped because the xenon atom tends to finish the outermost electronic shell by incorporating an electron from the neighboring xenon atom.

As the fifty percent-lifetime of 129I is comparatively shorter with a cosmological time scale (sixteen million many years), this demonstrated that only a short time experienced handed in between the supernova and some time the meteorites had solidified and trapped the 129I. These two situations (supernova and solidification of gas cloud) had been inferred to have occurred in the course of the early historical past of your Solar Process, as the 129I isotope was probable created Soon ahead of the Photo voltaic Technique was fashioned, seeding the photo voltaic fuel cloud with isotopes from a second resource. This supernova source may perhaps even have prompted collapse of your photo voltaic gas cloud.[eighty two][eighty three]
Atomic radius, non-bonded Fifty percent of the distance involving two unbonded atoms of the same element in the event the electrostatic forces are balanced. These values were identified applying quite a few diverse strategies.
Liquid or reliable xenon nanoparticles might be formed at room temperature by implanting Xe+ ions into a strong matrix. Lots of solids have lattice constants more compact than solid Xe. This leads to compression of the implanted Xe get more info to pressures Which might be adequate for its liquefaction or solidification.[51]
