neu.tron

n.Abbr. n（名詞）縮寫 n
An electrically neutral subatomic particle in the baryon family, having a mass ,839 times that of the electron, stable when bound in an atomic nucleus, and having a mean lifetime of approximately .0×03 seconds as a free particle. It and the proton form nearly the entire mass of atomic nuclei. See table at subatomic particle
