For other uses, see Neon (disambiguation). Chemical element with atomic number 10 (Ne) Neon, 10 Ne Neon Appearance colorless gas exhibiting an orange-red glow when placed in an electric field Standard ...
Neon's polarisability of 0.395 Å 3 is the second lowest of any element (only helium's is more extreme). Low polarisability means there will be little tendency to link to other atoms. [1] Neon has a Lewis basicity or proton affinity of 2.06 eV. [2] Neon is theoretically less reactive than helium, making it the least reactive of all the elements ...
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 ...
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 or argon are the most common gases used; krypton, xenon, and helium are used by artists for special purposes but are not used alone in normal signs. A premixed combination of argon and helium is often used in lieu of pure argon when a tube is to be installed in a cold climate, since the helium increases voltage drop (and thus power ...

1. Tennis Ball. Tennis balls are so useful that you may want to buy some to keep around the house even if you don’t play. For example, half a tennis ball can help screw open tight caps.
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.
