Editing Antimatter (section)

==Notation==
One way to denote an [[antiparticle]] is by adding a bar over the particle's symbol. For example, the proton and antiproton are denoted as {{Subatomic particle|proton}} and {{Subatomic particle|antiproton}}, respectively. The same rule applies if one were to address a particle by its constituent components. A proton is made up of  {{Subatomic particle|link=yes|Up quark}} {{Subatomic particle|link=no|Up quark}} {{Subatomic particle|link=yes|Down quark}} [[quark]]s, so an antiproton must therefore be formed from {{Subatomic particle|link=yes|Up antiquark}} {{Subatomic particle|link=no|Up antiquark}} {{Subatomic particle|link=yes|Down antiquark}} [[antiquark]]s. Another convention is to distinguish particles by positive and negative [[electric charge]]. Thus, the electron and positron are denoted simply as {{Subatomic particle|Electron}} and {{Subatomic particle|Positron}} respectively. To prevent confusion, however, the two conventions are never mixed.
