neutron
UK: ˈnjuːtrɒn | US: ˈnuːtrɑːn
n. an uncharged subatomic particle with a mass slightly greater than that of a proton, found in the nucleus of an atom.
The word "neutron" was coined in 1921 by physicist Ernest Rutherford, derived from "neutral" (from Latin neutrālis, meaning "neither one nor the other") + the suffix "-on" (used in physics to denote subatomic particles, e.g., proton, electron). The term reflects the particle's lack of electric charge, distinguishing it from the positively charged proton and negatively charged electron.
A neutron has no electric charge but contributes to the mass of an atom.
Neutrons stabilize the nucleus by balancing proton repulsion.
The collision released several free neutrons.
Neutron stars are incredibly dense remnants of supernovae.
Scientists use neutron scattering to study material structures.
