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 »

The average life span of a neon sign is eight to 15 years. Failure at this age is due to the burnout of the electrical components; the neon gas itself retains its ability to produce light for up to 50 years. More »

Neon is its own chemical element, not a compound of elements. Neon is an inert gas and part of the noble gases group in the periodic table. 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 »

Neon lights work by applying high voltage to the electrodes at each end of a sealed glass tube filled with low-pressure neon gas. This ionizes the neon and causes it to glow. More »

Neon belongs to a family of elements commonly known as the noble gases. These gases are renowned for their low levels of reactivity with other elements. The moniker "noble" indicates that they do not typically react with... More »
