[nōṓtrŏń, nyōṓ-]
(n.)An electrically neutral subatomic particle in the baryon family, having a mass 1,839 times that of the electron, stable when bound in an atomic nucleus, and having a mean lifetime of approximately 1.0 × 10 seconds as a free particle. It and the proton form nearly the entire mass of atomic nuclei.

Neutrons are uncharged particles found within atomic nuclei. Neutrons were discovered by James Chadwick in 1932. ... Experiments done at the Stanford Linear Accelerator Center in the late 1960's and early 1970's showed that neutrons are made from other particles called quarks. Neutrons are made from one 'up' quark and...

Neutrons and protons constitute almost all of an atom's mass. They stick together because of the strong nuclear force to form all the different kinds of atoms. ... Free neutrons easily pass through atoms, because they have no electrical charge, and so they form highly penetrating radiation, interacting with matter only...
