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 lights are created by creating a vacuum, which is an area that is empty of air, in a glass tube and then pumping specific gases, such as neon, mercury and argon, back into that tube. According to Harvard University'... More »

At the beginning of the 20th century, French engineer, chemist and inventor Georges Claude invented the neon lamp. He sent electricity into a tube of neon gas, which had been discovered by William Ramsey and M. Travers i... 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 »
