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 the other elements.
Neon is a nonmetallic element that is most commonly used in signs that light up with brightly glowing colors. These signs use various levels of ionization to achieve the proper excitement of the electrons in the element, which allow it to glow. The element neon was first discovered in 1898 by William Ramsay and Morris Travers in their attempt to locate the element residing between helium and argon on the periodic table.
