![]() Copyright © 2023, Columbia University Press. The Columbia Electronic Encyclopedia, 6th ed. Neon was discovered in 1898 by William Ramsay and M. ![]() Liquid neon is a particularly good cryogenic refrigerant since it will absorb more heat without vaporizing than an equal volume of liquid helium or liquid hydrogen. Neon finds use in lasers both as a light-emitting agent and as a coolant. It is used for particle detection in high-energy physics research. The noble gases are colourless, odourless, tasteless, nonflammable gases. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Morris Travers and William Ramsay of University College London discovered neon gas in 1898. ![]() Neon and Its History A brief description of what is neon gas has already been given. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. A bit later, we will look into the various uses of neon gas. It is also used in high-intensity beacons, in some electron tubes, in Geiger counters, in automotive ignition timing lights, and in high-voltage warning indicators. noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. Neon is a chemical element with the symbol Ne and atomic number 10. The greatest commercial use of neon is in advertising signs (see lighting). It is obtained as a byproduct in the production of liquid air. Neon is a rare gas present in the atmosphere to a very limited extent. Due to the fact that neon gas is a completely inert substance, there are no compounds made with this chemical element. A small amount of neon in a partially evacuated glass tube emits a bright reddish-orange glow while conducting electricity. It is one of the inert gases in Group 18 of the periodic table it does not form compounds in the normal chemical sense. Neon is a colorless, odorless, and tasteless gas. −246.048☌ density 0.8999 grams per liter at STP valence 0. Neon nē´ŏn, gaseous chemical element symbol Ne at.
