Neon is the tenth element on the periodic table, and it is the first of the noble gases to have a full 8-electron orbital. Neon produces a reddish color on "neon" lights, and is completely inert, so it has no electronegativity. At STP, neon is gaseous and has a density of 0.900 g/L. Ne melts at 24.55 K and boils at 27.10 K. The atomic mass of Ne is 20.1797
1) A type of discharge lighting generated by a high voltage across two electrodes at opposite ends of a long, thin glass tube filled with neon gas. Different colours can be obtained by mixing other gases, or by using fluorescent coatings. Mostly used for advertising signs - the glass tube is bent to form letters. 2) A small mains voltage indicator lamp.
a colorless odorless gaseous element that give a red glow in a vacuum tube; one of the six inert gasses; occurs in the air in small amounts
A glass vacuum tube filled with neon gas and phosphors formed into signs, letters or shapes.
Bulb that contains an inert gas (neon) that glows when voltage is applied
Neon lamps are cold cathode lamps lacking a phosphor coating. See cold cathode.
A chemical element with atomic number 10. Neon was discovered in 1898 by Alexander Ramsay and Morris William Travers in the residue of an experiment on a sample of hydrogen. The name neon is derived from neos, Greek for new. Symbol: Ne. Related to noble gases.
(Symbol Ne.) An inert gas that is the second member of the noble gas family, atomic number 10, atomic weight 20.183. It is a colorless, odorless, monatomic element found in the atmosphere to the extent of about 0.0018% by volume of dry air.
An inert element from Group O of the periodic table of chemical elements. Exists as a gas at normal temperatures and pressures. When ionized by current passing through it, as in neon signs, bulbs, pilot lights, test probes, etc, it produces a bright orange-red glow.
A gas sometimes used in diving.
Neon (IPA: ) is the chemical element that has the symbol Ne and atomic number 10. A very common element in the universe, it is rare on Earth. A colorless, nearly inert noble gas under standard conditions, neon gives a distinct reddish glow when used in vacuum discharge tubes and neon lamps.
