A positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element; the nucleus of the most common isotope of hydrogen; composed of two up quarks and a down antiquark
positively-charged subatomic particle that is found in the nucleus of an atom It has about 1800 times more mass than its negatively-charged electron counterpart
A positively charged particle that is a constituent of an atom It has a mass similar to a neutron
A proton is an atomic particle that has a positive electrical charge. a very small piece of matter with a positive electrical charge that is in the central part of an atom electron, neutron neutron (from protos; PROTO-). Stable subatomic particle (one of the baryons) with a unit of positive electric charge and a mass 1,836 times that of the electron. Protons are found in the atomic nucleus along with neutrons. For every nucleus of a given element, the number of protons is always the same; this number is the element's atomic number. A single proton is the nucleus of an atom of ordinary hydrogen; as such, it is identical to the hydrogen ion (H^+). Protons have antimatter counterparts (antiprotons), with the same mass but a negative charge. Protons are used as projectiles in particle accelerators to produce and study nuclear reactions. They are the chief constituent of primary cosmic rays and are among the products of radioactive decay (see radioactivity) and nuclear reactions
a fundamental particle with a positive charge commonly found in the nucleus of atoms
Particle found in a nucleus with a positive charge Number of these gives atomic number Back to top Q
A baryon with electric charge +1 Protons contain a basic structure of two up quarks and one down quark The nucleus of a hydrogen atom is a proton A nucleus with atomic number Z contains Z protons; therefore the number of protons is what distinguishes the different chemical elements
A subatomic, or elementary, particle with a single positive charge equal in magnitude to the charge of an ELECTRON and a mass of 1; very close to that of a NEUTRON; the nucleus of a HYDROGEN ATOM is composed of a single proton
The positively charged part of an atom The number of protons determines which element the particle is It is part of the nucleus More about protons
A positively charged particle that is found in the nucleus of an atom and has a mass approximately 1836 times that of an electron
a stable particle with positive charge equal to the negative charge of an electron
A positively charged particle of an atom The charge and relatively large mass (~1800 times that of an electron) of protons account for the Bragg peak effect
A baryon with electric charge +1 Protons contain a basic structure of two up quarks and one down quark The nucleus of a hydrogen atom is a proton A nucleus with atomic number Z contains Z protons; therefore the number of protons is what distinguishes the different chemical elements More Information: Hadrons
A positively charged elementary particle that forms the nucleus of the hydrogen atom and is a constituent particle of all nuclei
A particle of mass (approximately) unity carrying a unit positive charge; it is identical physically with the nucleus of the ordinary (light) hydrogen atom All atomic nuclei contain protons See Nucleus
{i} elementary particle in the nucleus of all atoms, elementary particle with a positive electrical charge
One of the basic particles which makes up an atom The proton is found in the nucleus and has a positive electrical charge equivalent to the negative charge of an electron and a mass similar to that of a neutron
One of the basic particles of the atomic nucleus ( the other is the neutron) Its charge is as large as that of the electron, but positive See also: Electron, Neutron
One of the basic particles that makes up an atom The proton is found in the nucleus and has a positive electrical charge equal to the negative charge of an electron and a mass similar to that of a neutron: a hydrogen nucleus
One of the elementary particles of nature The proton has a charge of 1 6 x 10-19 Coulombs and a mass of 1 67 x 10-27 kg, much higher than an electron The proton resides in the nucleus of an atom, sharing the space with neutrons, neutrally charged particles
A common subatomic particle found in the nucleus of every atom, often along with neutrons Made of two up quarks and one down quark, a proton has a positive charge
Protons are heavy nuclear particles carrying a positive electrical charge Along with neutrons, they are the principal components of atomic nuclei It has a mass of 1 67 x 10-24 grams, 1836 times the mass of an electron Protons are composed of two "up" quarks and one "down" quark
Any protein in the membrane of a cell or mitochondrion whose function is to move protons across the membrane and thus establish an electrochemical potential
