any atom in the ring of a cyclic compound that is not a carbon atom
heteroatom in American English
(ˌhetərouˈætəm)
noun
Chemistry
an atom other than carbon in the ring structure of a heterocyclic compound
Word origin
[1895–1900; hetero- + atom]This word is first recorded in the period 1895–1900. Other words that entered Englishat around the same time include: Marxism, apothecaries' measure, cutback, frame of reference, freewheelhetero- is a combining form meaning “different,” “other,” used in the formation of compoundwords. Other words that use the affix hetero- include: heterochromatic, heterochrony, heterodyne, heterogonous, heterogony
