There are 11 gases in the periodic table and they are: Hydrogen, Helium, Neon, Argon, Krypton, xenon, radon, chlorine, fluorine, oxygen and nitrogen :D.oble gases are elements that have all possible electron positions in the outer, or valence, shell filled. This makes them chemically non-reactive. They are found in group 18 â¦ on the periodic table (far right edge) of elements (He, Ne, Ar, Kr, Xe, and Rn). 3 people found this useful.
