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.

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.
