Neon was the second of these three rare gases to be discovered and was immediately recognized as a new element from its bright red emission spectrum. The name neon is derived from the Greek word, νέον, neuter singular form of νέος (neos), meaning 'new'. Neon is chemically inert, and no uncharged neon See more 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 … 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. … 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 … 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 A gas-phase mixture mainly of nitrogen, neon, and helium is withdrawn from the … See more Neon was discovered in 1898 by the British chemists Sir William Ramsay (1852–1916) and Morris Travers (1872–1961) in See more Neon is the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 refrigerating capacity (per unit volume) of liquid helium and three times that of liquid hydrogen. In most applications it is a … 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, See more blackall qld weather
