英英释意

1. an elementary particle with 0 charge and mass about equal to a proton; enters into the structure of the atomic nucleus

英文词源

neutron (n.): "electrically neuter particle of the atom," 1921, coined by U.S. chemist William D. Harkins (1873-1951) from neutral (adj.) + -on. First record of neutron bomb is from 1960. Neutron star attested from 1934, originally hypothetical; so called because it would be composed of neutrons.
