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 »

The most characteristic property of the noble gases is their extremely low chemical reactivity as compared to other elements. The noble gases all have a full set of electrons in their outer shells, so they have little te... More »

The noble gases are the elements found in group 18 on the periodic table. Some of the noble gases are helium, krypton, radon and neon. These gases are on the far right of the periodic table, due to their similar characte... 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 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 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 »

Neon has the chemical formula Ne and atomic number 10. At room temperature, neon exists in the gaseous phase, and it classifies as a noble gas because its outer electron shell contains a full octet of electrons. This pro... More »
