Protonens [[Atommodel (bølge)|3D sandsynlighedsfordeling]] kan f.eks. være [[torus]]- eller [[ært]]eformet, den kan selvfølgelig også være [[kugle]]formet.<ref>[http://www.sciencedaily.com/releases/2003/12/031205051520.htm 2003-12-05, Science Daily: Zooming In On A Proton Packed With Surprises] Citat: "...Depending on the angular momentum of the quarks, the proton could be spherical in shape or more like a doughnut, a pretzel or a peanut...Miller says the variety of shapes is nearly limitless, and depends on the momentum of the [[Kvark (fysik)|quarks]] and the [[vinkel|angle]] between the [[spin (fysik)|spin]] of the quark and the spin of the proton..."</ref><ref>[http://www.aip.org/enews/physnews/2003/split/647-1.html July 23, 2003, Physics News Update: The Proton has a Different Size in Different Nuclei] Citat: "...The kneading allows the constituent quarks inside the proton to spread out a bit at time, perhaps into a peanut shape, even though its average shape is round..."</ref><ref>[http://www.sciencedaily.com/releases/2006/06/060630083845.htm June 30, 2006, Science Daily: Ghostly Strange Quarks Influence Proton Structure]</ref>▼

Protonen beskrives oftest, som opbygget af 3 [[Kvark (fysik)|kvarker]]; 2 [[up-kvark]]er og en [[down-kvark]]. Dette er dog en forsimplet sandhed, som kun beskriver forholdet af partikler, som udgør protonens ladning. Up-kvarker har en ladning på
Protonen formodes at
<math>\hbox{p}^{+}\to\hbox{e}^{+}\;+\;\hbox{π}^{0}</math><br/>
Pionen henfalder øjeblikkeligt selv;<br/>
<math>\hbox{π}^{0}\to\hbox{2γ}</math>
