Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements … See more Neon was discovered in 1898 by the British chemists Sir William Ramsay (1852–1916) and Morris Travers (1872–1961) in London. Neon was discovered when Ramsay chilled a sample of air until it … See more Neon is the second-lightest noble gas, after helium. It glows reddish-orange in a vacuum discharge tube. It has over 40 times the … See more Neon is the first p-block noble gas, and the first element with a true octet of electrons. It is inert: as is the case with its lighter analogue, helium, no strongly bound neutral See more Neon is produced from air in cryogenic air-separation plants. A gas-phase mixture mainly of nitrogen, neon, and helium is withdrawn from the … See more Neon has three stable isotopes: Ne (90.48%), Ne (0.27%) and Ne (9.25%). Ne and Ne are partly primordial and partly nucleogenic (i.e. made by nuclear reactions of other nuclides with neutrons or other particles in the environment) and their variations in See more Stable isotopes of neon are produced in stars. Neon's most abundant isotope Ne (90.48%) is created by the nuclear fusion of carbon and carbon in the carbon-burning process of stellar nucleosynthesis. This requires temperatures above 500 megakelvins, … See more Neon is often used in signs and produces an unmistakable bright reddish-orange light.
