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 ...
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."
In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive. From a thermodynamic perspective, a substance is inert, or nonlabile, if it is thermodynamically unstable (positive standard Gibbs free energy of formation) yet decomposes at a slow, or negligible rate.

Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at
Atomicity is the total number of atoms present in a molecule of an element. For example, each molecule of oxygen (O 2) is composed of two oxygen atoms.Therefore, the atomicity of oxygen is 2.
