The formation of xenon
Xenon is a rare gas, one of the 18th group elements in the periodic table, colorless, odorless, tasteless, chemically inactive, exists in the air, every 100ml of air contains xenon 0.0087ml. Xenon was discovered by Ramch and Travis at University College London in July 1898, having previously extracted neon, argon, and krypton from the air, and wondering whether it contained other gases, the industrialists gave them a new liquid air machine, with which they extracted more of the noble gas krypton. After several distillations, they finally isolated a heavier gas that glowed pretty blue in the vacuum tube. They realized that he was another member of the inert group of gas elements, which he chose as the name xenon because it was chemically inert.
The role of xenon in life
Xenon is widely used in electronics, optical power industry, but also used in gas lasers and other ion streams, xenon filled bulbs with the same power filled argon bulbs compared with a high luminous rate, small size, long life, power saving and other advantages, hernia lamps have a very high luminous intensity, a single lamp of 60,000 watts of brightness, equivalent to nine hundred hundred watts of ordinary bulbs, Because xenon has an almost continuous spectrum, it can produce similar daylight and bright white lights under the action of high voltage arc discharge, this long arc xenon lamp, commonly known as artificial small sun, because of the fog transmission ability is particularly strong, can be used as a fog navigation light, xenon flash color is good, used for shooting color movies, line lamp can emit ultraviolet light, in medical applications, it is also useful. Xenon isotopes are used to measure cerebral blood flow, study lung function, and calculate insulin secretion. After the concave focus, it can generate 2500 degrees high temperature, which can be used for welding or cutting refractory metals such as titanium molybdenum, etc., but it is still a deep anesthetic without side effects, it can dissolve in the oil of the cell to cause cell expansion and anesthesia, so that the role of nerve endings temporarily stop, but also can absorb X-rays, and first used as X-ray shielding. Xenon is also widely used in nuclear reactors and high energy physics.
