neu·tron

 (no͞o′trŏn′, nyo͞o′-)
n. Abbr. n
The electrically neutral nucleon, a baryon composed of two down quarks and one up quark, which has a mass 1,839 times that of an electron, is stable when bound in an atomic nucleus, but has a mean lifetime of 886 seconds as a free particle. It is a basic component of all atomic nuclei except the protium isotope of hydrogen.

neutron

(ˈnjuːtrɒn)
n
(General Physics) physics a neutral elementary particle with a rest mass of 1.674 92716 × 10–27 kilogram and spin ; classified as a baryon. In the nucleus of an atom it is stable, but when free it decays
[C20: from neutral, on the model of electron]

neu•tron

(ˈnu trɒn, ˈnyu-)

n.
an elementary particle found in most atomic nuclei, having no charge, mass slightly greater than that of a proton, and spin of ½. Symbol: n

neu·tron

(no͞o′trŏn′)
An electrically neutral subatomic particle that is part of the nucleus of an atom and has a mass slightly greater than that of a proton. 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. See more at atom.

neutron

1. One of the three basic particles in an atoms. It is found in the nucleus and has zero charge.
2. A subatomic particle with roughly the mass of a proton and no electric charge.
