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 remaining rare inert elements in dry air after the removal of nitrogen, oxygen, argon, and carbon dioxide.
William Ramsay and Morris Travers discover the noble gases krypton (May 30), neon (June 7) and xenon (July 12) at University College London. [4] [5] July 28 – Marie and Pierre Curie announce (at the French Academy of Sciences) discovery of a substance they call Polonium.

The discovery of neon in 1898 by British scientists William Ramsay and Morris W. Travers included the observation of a brilliant red glow in Geissler tubes. [15] Travers wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."

Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals called phosphors are used to produce other colors, such as hydrogen (purple-red), helium (yellow or pink), carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or ...
Sir William Ramsay KCB FRS FRSE (/ ˈ r æ m z i /; 2 October 1852 – 23 July 1916) was a Scottish chemist who discovered the noble gases and received the Nobel Prize in Chemistry in 1904 "in recognition of his services in the discovery of the inert gaseous elements in air" along with his collaborator, John William Strutt, 3rd Baron Rayleigh, who received the Nobel Prize in Physics that same ...
Nov. 14—The 86-year-old Federal Building in downtown Mesa officially has begun a new life as an event space called The Post after languishing largely unused for two decades. In 2001, the U.S ...
