Xenon is a colorless, dense, odorless noble gas found in Earth’s atmosphere in trace amounts. It has an atomic number of 54; its nucleus is, its nucleus contains 54 protons, and its atomic number is Xe. It was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers in 1898.
About Xenon in brief
Xenon is a colorless, dense, odorless noble gas found in Earth’s atmosphere in trace amounts. Xenon is used in flash lamps and arc lamps, and as a general anesthetic. It is used to search for hypothetical weakly interacting massive particles and as the propellant for ion thrusters in spacecraft. Naturally occurring xenon consists of seven stable isotopes and two long-lived radioactive isotopes. More than 40 unstable xenon isotopes undergo radioactive decay, and the isotope ratios of xenon are an important tool for studying the early history of the Solar System. Radioactive xenon-135 is produced by beta decay from iodine-135, and is the most significant neutron absorber in nuclear reactors. At standard temperature and pressure, pure xenon has a density of 561kgm3, about 4.5 times the density of the atmosphere at sea level. Liquid xenon density is up to 100gmL, with the maximum point at the triple point of the xenon nucleus. It has an atomic number of 54; its nucleus is, its nucleus contains 54 protons, and its atomic number is Xe. It was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers in September 1898, shortly after their discovery of the elements krypton and neon. The first excimer laser design used a xenon dimer molecule as the lasing medium. The earliest laser designs used xenon flash lamps as pumps. By 1971, more than 80 xenon compounds were known. In November 1989, IBM scientists demonstrated a technology capable of manipulating individual atoms in atoms called IBM scanning tunneling microscope program called xenon.
It used a chilled crystal of 35 individual atoms on a substrate of nickel to spell out the first letter of the company’s initialism, “Xe” It was the first time that atoms had been positioned precisely on a flat surface on a surface that had been precisely positioned on the surface of a flat company. The name xenon comes from the Greek word xénon, neuter singular form of xénos, meaning ‘foreign’,’strange’, or ‘guest’, and the word xenon is the name of a type of chemical compound that can be synthesized. In 1902, Ramsay estimated the proportion of Xenon in the Earth’s Atmosphere to be one part in 20 million. In 1939, American physician Albert R. Behnke Jr. began exploring the causes of drunkness in deep-sea divers. He tested the effects of varying the breathing mixtures on his subjects, and discovered that this caused the divers to perceive a change in depth. In 1951, American anesthesiologist Stuart C. Cullen, who successfully used it with two patients, used it as a surgical anesthetic, and it was first used as an anesthetic in 1951 by American medical researcher John H. Lawrence, who experimented on mice. In 1962, Neil Bartlett discovered that the gas platinum hexafluoride was a powerful oxidizing agent that could oxidize oxygen gas. Bartlett mixed the two gases and produced the first known compound of a noble gas, xenon hexafLUoplatinate.
