![]() ![]() Copyright © 2023, Columbia University Press. The Columbia Electronic Encyclopedia, 6th ed. Neon was discovered in 1898 by William Ramsay and M. Its symbol is: H He Ho Hy Heres a fun fact for you. 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. Hydrogen is the most abundant element in the universe. Neon is a rare gas with a closely packed cubic structure composed of molecules that contain a single atom of this chemical element. 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. 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. The greatest commercial use of neon is in advertising signs (see lighting). It is a completely inert gas, meaning that it will not combine with other elements or. A light and stable element, neon is mainly used to illuminate neon signs for advertising. Under standard conditions the element neon is a colorless odorless gas. Note: The above text is excerpted from the Wikipedia article. Neon (IPA: /nän/) is a chemical element in the periodic table that has the symbol Ne and atomic number 10. It is obtained as a byproduct in the production of liquid air. Neon is the chemical element in the periodic table that has the symbol Ne and atomic number 10. Neon is a rare gas present in the atmosphere to a very limited extent. It is the first element forming a true octet of electrons and hence is inert just like its lighter analogue, helium. A small amount of neon in a partially evacuated glass tube emits a bright reddish-orange glow while conducting electricity. Physical Characteristics Neon is a noble gas belonging to first p-block of periodic table. 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. ![]()
