Neon is a chemical element; it has symbol Ne and atomic number 10. It is the second noble gas in the periodic table. [13] Neon is a colorless, odorless, inert monatomic gas under standard conditions, with approximately two-thirds the density of air. Neon was discovered in 1898 alongside krypton and xenon, identified as one of the three ...
Neon was discovered in 1898 by the British scientists William Ramsay and Morris W. Travers. After obtaining pure neon from the atmosphere, they explored its properties using an "electrical gas-discharge" tube that was similar to the tubes used for neon signs today.
Thomson's separation of neon isotopes by their mass was the first example of mass spectrometry, which was subsequently improved and developed into a general method by F. W. Aston and by A. J. Dempster.
1910 Georges Claude demonstrates neon lighting at the Paris Motor Show. 1912 Charles P. Steinmetz invents the metal-halide lamp. [11] 1913 Irving Langmuir discovers that inert gas could double the luminous efficacy of incandescent lightbulbs. 1917 Burnie Lee Benbow patents the coiled coil filament. 1920 Arthur Compton invents the sodium-vapor ...
Morris Travers. Morris William Travers, FRS (24 January 1872 – 25 August 1961) was an English chemist who worked with Sir William Ramsay in the discovery of xenon, neon and krypton. [1] His work on several of the rare gases earned him the name Rare Gas Travers in scientific circles. [2] He was the founding director of the Indian Institute of ...
Perey discovered it as a decay product of 227 Ac. [172] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well.

A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
