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 proton–electron mass ratio). Protons and neutrons, each with masses of approximately one atomic … Visa mer 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 a proton are held together by the strong force, … Visa mer 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 other particles. Free protons are found … Visa mer 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 … Visa mer 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 … Visa mer The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period. As early as 1815, William Prout proposed that all atoms are composed … Visa mer 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 … Visa mer Although protons have affinity for oppositely charged electrons, this is a relatively low-energy interaction and so free protons must lose sufficient velocity (and Visa mer WebbMy research activity can be divided in five issues.

WebbHowever, the mass of the proton means that the energy loss by Bremsstrahlung is insignificant in comparison to the energy loss by electron interactions and has no clinical consequences. As well as Coulomb interactions, protons undergo elastic and non-elastic collisions with the atomic nucleus.
