neutron
weight: 1.6749286*10^-27kg a neutral hadron that is stable in the atomic nucleus but decays into a protron, an electron and an antineutrino with a mean life of 12 minutes outside the nucleus. neutrons exist in all atomic nuclei except normal hydrogen. reported in 1932 by james chadwick.

Neutron
An uncharged elementary particle, with a mass slightly greater than that of the proton, found in the nucleus of every atom heavier than hydrogen.
An uncharged elementary particle, with a mass slightly greater than that of the proton, found in the nucleus of every atom heavier than hydrogen.
Neutron, thermal
A neutron that has (by collision with other particles) reached an energy state equal to that of its surroundings, typically on the order of 0.025 eV (electron volts).

Neutron
An elementary particle which possesses a charge of zero and mass a little greater than the proton. It is composed of three quarks and is a constituent of every atomic nucleus except the lightest hydrogen isotope. Once freed from an atomic nucleus, a neutron will undergo radioactive decay via the weak nuclear force into a proton , an electron (negative beta particle) and an antimatter neutrino (antineutrino) in a mean time of just over 900 seconds. Thus there are no free neutrons in space.

neutron
a part of the nucleus of all atoms except hydrogen. Under certain conditions, neutrons can be emitted from a substance when its nucleus is penetrated by gamma particles from a highly radioactive source. This property is used in neutron logging. (See radioactivity logging.)

Neutron
a small atomic particle possessing no electrical charge typically found within an atom's nucleus. Neutrons are, as the name implies, neutral in their charge. That is, they have neither a positive nor a negative charge. A neutron has about the same mass as a proton. See also alpha particle, beta particle, gamma ray, nucleon, x-ray.
