| neutron |
A baryon with electric charge zero; it has the basic structure of two down quarks and one up quark (held together by gluons). The neutral component of an atomic nucleus is made from neutrons. Different isotopes of the same element are distinguished by having different numbers of neutrons in their nuclei.

| neutron |
Ostensibly an elementary particle found in most atomic nuclei, having no charge, mass slightly greater than that of a proton, and experimentally demonstrating a spin of 1/2. The neutron is considered to be a fermion because of its measured spin quantity. The free neutron has a half life of approximately 1010 seconds and decays into a proton, an electron, and an antineutrino. ...

One of the basic particles which make up an atom. A neutron and a proton have about the same weight, but the neutron has no electrical charge. In our diagrams, a neutron is represented by this:
