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 … See more

Neon is the second-lightest noble gas, after helium. Like other noble gases, neon is colorless and odorless. It glows reddish-orange in 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 analog, See more

Two quite different kinds of neon lighting are in common use. Neon glow lamps are generally tiny, with … 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 See more

Neon is produced from air in cryogenic air-separation plants. A gas-phase mixture mainly of nitrogen, neon, helium, and hydrogen is withdrawn from the main condenser at the top … See more
