| 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. |
| The rightmost column in any self-respecting periodic table should certainly be the 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. |
| Two copies of the column with the noble gases, such as helium and neon, bracket the table like bookends. |
| In the early 1960s, a number of chemists found ways of making compounds of some noble gases, including radon, xenon, and krypton. |
