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."
Neon compounds are chemical compounds containing the element neon (Ne) with other molecules or elements from the periodic table. Compounds of the noble gas neon were believed not to exist, but there are now known to be molecular ions containing neon , as well as temporary excited neon-containing molecules called excimers .
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 ...
The inertness of noble gases makes them useful whenever chemical reactions are unwanted. For example, argon is used as a shielding gas in welding and as a filler gas in incandescent light bulbs. Helium is used to provide buoyancy in blimps and balloons. Helium and neon are also used as refrigerants due to their low boiling points.
The remains of former US President Jimmy Carter are carried by an honor guard on departure from the Washington National Cathedral in Washington, DC, after a State Funeral Service on January 9, 2025.
Ice can be used for back discomfort when there is a clear injury or irritation after moving in a suboptimal way that generates pain, says Dr. Shah. ... A common finding with chronic back pain is ...
The compound [Xe 2] + [Sb 4 F 21] − contains a Xe–Xe bond, which is the longest element-element bond known (308.71 pm = 3.0871 Å). [14] Short-lived excimers of Xe 2 are reported to exist as a part of the function of excimer lasers. [citation needed]
