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 possibility that it can form compounds with fluorine.
Neon was discovered by Sir William Ramsay and Morris Travers in 1898 during their studies of liquefied air. It is a nonmetal gas with an atomic number of 10 and the atomic symbol of Ne. Its lack of negativity means that it does not share electrons with other elements to form bonds. Neon's name is derived from the Greek word "neos," which means new. Neon is often used in signs for advertising.
