| In the same year, Ramsay and Travers discovered two other noble gases, xenon and neon. |
| The noble gases helium, neon, argon, krypton, and xenon display fairly simple chemistry in material of solar composition. |
| Neon is the second element in Group 18 of the periodic table, a group of elements known as the inert or noble gases. |
| Four important chemical family names of elements still widely used are the alkali metals, the alkaline earths, the halogens, and the noble gases. |
| The meteorite is composed of an abundance of black glass, with noble gases trapped inside. |
| The rightmost column in any self-respecting periodic table should certainly be the noble gases. |
