Etymology

edit

From Middle English attome, from Middle French athome, from Latin atomus (“smallest particle”), from Ancient Greek ἄτομος (átomos, “indivisible”), from ἀ- (a-, “not”) ‎ τέμνω (témnō, “I cut”). Atoms are so named because historically the notion was that they were indivisible, given that chemically they are indeed so; the splitting of atoms awaited a later era of science and technology, and nonchemical means.
