Neon (Ne) is the most common noble gas used in neon signs. The term "neon signs" comes from its frequent use as a lighting agent. More »

Neon lights use glass tubes filled with a low-pressure gas that glows under high voltage. A sign maker shapes one or more of the tubes as desired, adds a fluorescent coating and then fills them with special gases. This a... More »

Neon has no electronegativity on the Pauling scale because it is a noble gas and has a full set of electrons in its outer shell. As of June 2014, there are no known compounds that contain neon, although there is a possib... More »

Neon is a nontoxic, colorless gas that forms no known stable compounds. It is the second lightest noble gas. If placed in a vacuum discharge tube, neon has a reddish-orange glow when an electric current is passed through... More »
