neutron

 [noo´tron]
an electrically neutral or uncharged particle of matter existing along with protons in the atoms of all elements except the mass 1 isotope of hydrogen.

neu·tron (n),

(nū'tron),
An electrically neutral particle in the nuclei of all atoms (except hydrogen-1) with a mass slightly greater than that of a proton; in isolation, has a half-life of about 10.3 minutes.
[L. neuter, neither]

/neu·tron/ (noo´tron) an electrically neutral or uncharged particle of matter existing along with protons in the nucleus of atoms of all elements except the mass 1 isotope of hydrogen. Symbol n.

neutron

[n(y)o̅o̅′tron]
Etymology: L, neuter, neither; Gk, elektron, amber
(in physics) an elementary particle that is a constituent of the nuclei of all elements except the isotopic form of hydrogen 1H. It has no electric charge and has approximately the same mass as a proton. Compare electron, proton. See also atom.

neutron

As defined in magnetic resonance, a neutron is an uncharged neutral particle located in the nucleus of an atom which serves as a stabiliser.

neu·tron

(nū'tron)
An electrically neutral particle in the nuclei of all atoms (except hydrogen-1) with a mass slightly larger than that of a proton; in isolation, it breaks down to a proton and an electron with a half-life of about 10.3 minutes.
[L. neuter, neither]

neutron (nōōˑ·trn),

n the neutral subatomic particle located within the nucleus of an atom. Its mass is equivalent to that of a proton.

neu·tron

(nū'tron)
An electrically neutral particle in the nuclei of all atoms (except hydrogen-1) with a mass slightly larger than that of a proton; in isolation, it breaks down to a proton and an electron with a half-life of about 10.3 minutes.
[L. neuter, neither]

neutron (noo´tron),

n an elementary particle with approximately the mass of a hydrogen atom but without any electrical charge; one of the constituents of the atomic nucleus.
neutron activation analysis,
n an activation analysis in which the specimen is bombarded with neutrons. Identification is made by measuring the resulting radioisotopes.
