neutron
[ noo-tron, nyoo- ]
noun
- an elementary particle having no charge, mass slightly greater than that of a proton, and spin of ½: a constituent of the nuclei of all atoms except those of hydrogen. : n
neutron
/ ˈːٰɒ /
noun
- physics a neutral elementary particle with a rest mass of 1.674 92716 × 10 –27kilogram and spin 1 2 ; classified as a baryon. In the nucleus of an atom it is stable, but when free it decays
neutron
/ Դ̅̅′ٰŏ′ /
- An electrically neutral subatomic particle in the baryon family, having a mass of 1.674 × 10 -24 grams (1,838 times that of the electron and slightly greater than that of the proton). Neutrons are part of the nucleus of all atoms, except hydrogen, and have a mean lifetime of approximately 1.0×10 3 seconds as free particles. They consist of a triplet of quarks, including two down quarks and one up quark, bound together by gluons. In radioactive atoms, excess neutrons are converted to protons by beta decay. Beams of neutrons from nuclear reactors are used to bombard the atoms of various elements to produce fission and other nuclear reactions and to determine the atomic arrangements in molecules.
