A proton is a stable subatomic particle, symbol p, H +, or 1 H + with a positive electric charge of +1 e (elementary charge).Its mass is slightly less than the mass of a neutron and approximately 1836 times the mass of an electron (the proton-to-electron mass ratio).
Except for the proton and neutron, all other hadrons are unstable and decay into other particles in microseconds or less. A proton is made of two up quarks and one down quark, while the neutron is made of two down quarks and one up quark. These commonly bind together into an atomic nucleus, e.g. a helium-4 nucleus is composed of two protons and ...
Protoscience as a research field with the characteristics of an undeveloped science appeared in the early 20th century. [2] [3] In 1910, Jones described economics: I confess to a personal predilection for some term such as proto-science, pre-science, or nas-science, to give expression to what I conceive to be the true state of affairs, which I take to be this, that economics and kindred ...
In chemistry, the hydron, informally called proton, [2] is the cationic form of atomic hydrogen, represented with the symbol H +The general term "hydron", endorsed by IUPAC, encompasses cations of hydrogen regardless of isotope: thus it refers collectively to protons (1 H +) for the protium isotope, deuterons (2 H + or D +) for the deuterium isotope, and tritons (3 H + or T +) for the tritium ...
A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space. [1] Due to its extremely high charge density of approximately 2×10 10 times that of a sodium ion, the bare hydrogen ion cannot exist freely in solution as it ...
An animation of the strong interaction between a proton and a neutron, mediated by pions. The colored small double circles inside are gluons . In nuclear physics and particle physics , the strong interaction , also called the strong force or strong nuclear force , is a fundamental interaction that confines quarks into protons , neutrons , and ...

When a proton encounters its antiparticle (and more generally, if any species of baryon encounters the corresponding antibaryon), the reaction is not as simple as electron–positron annihilation. Unlike an electron, a proton is a composite particle consisting of three "valence quarks" and an indeterminate number of "sea quarks" bound by gluons.
