atom

== English == === Alternative forms === === Etymology === 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, “to cut”, o-grade in τομ-) +‎ -ος (-os). Atoms are so named because they were historically thought up as to be the smallest unit of matter, and thus indivisible. Doublet of atomus. === Pronunciation === IPA(key): /ˈætəm/ (General American) IPA(key): [ˈæɾm̩], [ˈæɾəm] Rhymes: -ætəm Homophone: Adam (in dialects with flapping) Hyphenation: at‧om === Noun === atom (plural atoms) (chemistry, physics) The smallest possible amount of matter which still retains its identity as a chemical element, now known to consist of a nucleus surrounded by electrons.
