One or more protons are present in the nucleus of every atom. They provide the attractive electrostatic central force that binds the atomic electrons. Visa mer 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 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 … 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 … 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 nuclei have definite boundaries. … 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 of hydrogen atoms (which he called "protyles"), based on a simplistic … Visa mer In quantum chromodynamics, the modern theory of the nuclear force, most of the mass of protons and neutrons is explained by 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 kinetic energy) in order to become closely associated and bound to electrons.
