A measure in the stiffness of a substance. It provides a measure of how tricky it can be to increase a material, with a value provided by the ratio of tensile toughness to tensile strain.

xenon - a colorless odorless inert gaseous element taking place in the earth's environment in trace quantities
In 1939, American health practitioner Albert R. Behnke Jr. started exploring the results in of "drunkenness" in deep-sea divers. He examined the effects of different the breathing mixtures on his subjects, and learned that this induced the divers to understand a change in depth. From his effects, he deduced that xenon fuel could serve as an anesthetic.
[179] Xenon is non-harmful, although it does dissolve in blood and belongs to some select team of substances that penetrate the blood–brain barrier, leading to mild to complete surgical anesthesia when inhaled in higher concentrations with oxygen.[178]
air - a mixture of gases (In particular oxygen) required for breathing; the things which the wind is made of; "air air pollution"; "a scent of chemical substances while in the air"; "open up a window and Permit in a few air"; "I want some clean air"
argonon, inert gasoline, noble fuel - any of your chemically inert gaseous elements on the helium team in the periodic table
Liquid xenon is Employed in calorimeters[171] to measure gamma rays, and as a detector of click here hypothetical weakly interacting enormous particles, or WIMPs. Every time a WIMP collides which has a xenon nucleus, idea predicts it'll impart ample Strength to bring about ionization and scintillation.
The pace of audio in xenon fuel (169Â m/s) is below that in air[180] since the typical velocity of your weighty xenon atoms is lower than that of nitrogen and oxygen molecules in air. As a result, xenon vibrates far more gradually during the vocal cords when exhaled and creates reduced voice tones, an impact reverse on the high-toned voice made in helium. Like helium, xenon will not fulfill the body's need to have for oxygen, and it's both equally a simple asphyxiant and an anesthetic a lot more highly effective than nitrous oxide; As a result, and since xenon is expensive, many universities have prohibited the voice stunt being a normal chemistry demonstration.
Nuclei of two on the stable isotopes of xenon, 129Xe and 131Xe, have non-zero intrinsic angular momenta (nuclear spins, suited to nuclear magnetic resonance). The nuclear spins is usually aligned outside of common polarization degrees through circularly polarized light-weight and rubidium vapor.[seventy two] The ensuing spin polarization of xenon nuclei can surpass fifty% of its most doable value, enormously exceeding the thermal equilibrium price dictated by paramagnetic figures (generally 0.
A percentile rank for the political stability of the very best generating state, derived from World Bank governance indicators.
Xenon and the opposite noble gases ended up for many years thought to be entirely chemically inert and not able to kind compounds. However, although instructing for the College of British Columbia, Neil Bartlett found out that the gas platinum hexafluoride (PtF6) was a strong oxidizing agent that would oxidize oxygen gas (O2) to form dioxygenyl hexafluoroplatinate (O+
Atomic radius, non-bonded Fifty percent of the distance in between two unbonded atoms of the identical component when the electrostatic forces are well balanced. These values ended up established utilizing a number of different solutions.
In an analogous way, xenon isotopic ratios such as 129Xe/130Xe and 136Xe/130Xe are a powerful Instrument for knowledge planetary differentiation and early outgassing.[21] For example, the atmosphere of Mars displays a xenon abundance comparable to that of Earth (0.08Â parts per million[84]) but Mars displays a larger abundance of 129Xe compared to the Earth or even the Sunshine.
