Discovery Information
Who: Sir William Ramsay , M.W. Travers
When: England
Where: 1898
Name Origin
Greek: neos (new).
Sources
It can be prepared by liquification of air and separated from other elements by fractional distillation.
Uses
In a vacuum tube, neon glows reddish orange, thus, the invention of neon lights. Neon has also been used to make lightening arrestors, voltage detectors and TV tubes.
Notes
While it is inert, there have been reports of it combining with fluorine. Neon may also form ions in combination with other noble gases (NeAr, HeNe, Ne2 and with hydrogen (NeH). It also forms an unstable hydrate, so it is not nearly as inert as one might think. In a vacuum discharge tube, neon glows reddish orange. Of all the rare gases, the discharge of neon is the most intense at ordinary voltages and currents. It is present in the atmosphere as 1 part in 65000.
Liquid neon has over 40 times more refrigerating capacity than liquid helium, and more than 3 times that of liquid hydrogen.
