In quantum chromodynamics, the modern theory of the nuclear force, most of the mass of protons and neutrons is explained by special relativity. The mass of a proton is about 80–100 times greater than the sum of the rest masses of its three valence quarks, while the gluons have zero rest mass. The extra energy of … See more A proton is a stable subatomic particle, symbol p , H , or H with a positive electric charge of +1 e (elementary charge). Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the See more The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period. As early as 1815, See more The problem of defining a radius for an atomic nucleus (proton) is similar to the problem of atomic radius, in that neither atoms nor their nuclei have definite boundaries. … See more Atomic number In chemistry, the number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element to which the atom belongs. For example, the atomic number of chlorine is 17; this means that … See more Protons are spin-1/2 fermions and are composed of three valence quarks, making them baryons (a sub-type of hadrons). The two up quarks and one down quark of … See more The free proton (a proton not bound to nucleons or electrons) is a stable particle that has not been observed to break down spontaneously to … See more Although protons have affinity for oppositely charged electrons, this is a relatively low-energy interaction and so free protons must lose sufficient velocity (and kinetic energy) in order to become closely associated and bound to electrons. High energy protons, … See more WebAn atom of Sodium has 11 protons and a mass number of 13. How many neutrons does it have? Question #24d91 What parts make up the nucleus?

In the universe, protons are abundant, making up about half of all visible matter.It has a positive electric charge (+1e) and a rest mass equal to 1.67262 × 10 −27 kg (938.272 MeV/c 2)— marginally lighter than that of the neutron but nearly 1836 times greater than that of the electron.
WebOct 8, 2024 · 8. Protons have that much more mass, not volume. The two are very different properties - in fact, for small particles like protons and electrons, bigger mass means occupying less space (or more accurately, less uncertainty in their position - neither electrons nor protons are little balls). – Luaan.
