'''Atomus''' {{victio|atomus|i|f}} (scil. ''hyle'') ([[Graece]]: ἄτομος, ''atomos'' 'individuus') est principalis [[materia (physica)|materiae]] pars, quae in denso medio [[nucleus atomicus|nucleo]] consistit, a [[nubes electronum|nube]] [[electron]]um [[onus electricum|negative oneratorum]] cincto. [[Nucleus atomicus]] commixtionem continet [[proton]]um positive oneratorum et [[electricitas|electrice]] neutra [[neutron]]a (excepto casu [[hydrogenium-1|hydrogenii-1]], solum stabilis [[nuclidum|nuclidi]] nulla neutrona habentis). Electrona atomi ad nucleum a [[vis electromagnetica|vi electromagnetica]] conligantur. Similiter, atomi inter se ligati manere possunt, [[molecula]]m formantes. Atomus quiquae aequalem protonum electronumque numerum continet electrice est neuter; aliter, onus vel positivum vel negativum habet, et ergo est [[ion]]. Atomi in genera describuntur secundum numerum protonum neutronumque in nucleo habitum: [[numerus atomicus|numerus protonum]] [[elementum chemicum]] constituit, et [[numerus neutronum]] elementi [[isotopus|isotopum]] constituit.<ref name=leigh1990>G. J. Leigh, ''International Union of Pure and Applied Chemistry, Commission on the Nomenclature of Inorganic Chemistry, [[Nomenclature of Organic Chemistry]]: Recommendations 1990'' (Oxoniae: Blackwell Scientific Publications, 1990), p. 35: "An atom is the smallest unit quantity of an element that is capable of existence whether alone or in chemical combination with other atoms of the same or other elements."</ref> Protona et neutrona e [[quarcum|quarciis]] deducuntur.
