| In the course of the 20th century, science successively named electrons, protons, neutrons, and quarks. |
| Yet experiments indicated that quarks within protons were only loosely bound together. |
| They would like to use their carborane acids to bind protons to atoms of the inert gas xenon. |
| Weak acids have dissociable protons like strong acids, but they simply do not dissociate completely. |
| That process would briefly liberate the quarks and gluons that make up protons and neutrons. |
| The protons and neutrons in the nucleus are made of elementary particles called quarks. |
