WebApr 21, 2024 · The proton mass is 938 MeV. People often claim that (A) The proton is a bound state of two up quarks and one down quark, with the three quarks contributing a total rest mass of $2 \times (2.2 \text{ MeV}) + (4.7 \text{ MeV}) = 9.1 \text{ MeV}$ (about 1% of the proton mass), and the other 99% coming from "QCD binding energy". People further ... WebHowever, the actual mass of the proton is 1.6726 × 10 −27 kg. That is, the mass of a proton is approximately 1837 times greater than the mass of an electron. Proton is a positively charged particle. Its actual charge is +1.602 × 10 −19 coulombs. The diameter of a proton particle is about 2.4 × 10 −13 cm.
