'''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.
