Linguistic Origin & Historical Etymology

Coined in 1921 by American physical chemist William Draper Harkins, the term derives from the Latin 'neuter' (meaning 'neither') combined with the Greek-derived chemical suffix '-on' (as used in electron and proton). It entered standard scientific English following the experimental discovery of the particle by James Chadwick in 1932.
