Neon (chemical symbol Ne, atomic number 10) is the fourth most abundant chemical element in the universe, but it is just a trace element in the air. As a member of the noble gas series, it is nearly inert. Under ordinary conditions, it is colorless, but in a vacuum discharge tube, it gives a reddish-orange glow. Consequently, the main use of neon is to make flashy signs for advertising.
