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 molecules containing neon have been identified. The ions [NeAr] , [NeH] , and [HeNe] have been observed from optical and mass spectrometric … 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 carbon in the carbon-burning process See more Neon is often used in signs and produces an unmistakable bright reddish-orange light. Although tube lights with other colors are often called "neon", they use different noble gases or varied colors of fluorescent lighting. Neon is used in 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 … 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 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 A gas-phase mixture mainly of nitrogen, neon, and helium is withdrawn from the main condenser at the top of the high … See more WebA large flask with a volume of 936 mL is evacuated and found to have a mass of 134.66 g. It is then filled to a pressure of 0.967 atm at 31C with a gas of unknown molar mass and then reweighed to give a new mass of 135.87 g. What is the molar mass of this gas?
