Protonens masse er <math>1,672621154 \cdot 10^{-27}</math> kg (bestemt 2008.11), hvilket svarer til <math>938,271742</math> [[elektronvolt|MeV]]/[[Lysets hastighed|c]]², eller 1,007276 [[Atommasseenhed|u]], og dens elektriske ladning er <math>1,602 \cdot 10^{-19}</math> [[Coloumb]]. Denne værdi kaldes [[elementarladning]]en og betegnes ''e''.

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>
