Türkçe - İngilizce
proton
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 sub-particle of an atom that contains a positive charge
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 positively charged particle that is located in the nucleus of an atom
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
Subatomic particle with a positive charge that is nucleus of hydrogen atom
a sub-atomic particle, positively charged, in the nucleus of atoms
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
