Also, since it is an American-English +dictionary, it spells "aluminium" (pronounced "al-yu-min-ee-um") as +"aluminum" ("a-loo-mi-num") since this is how Americans pronounce it. + +To address these issues, this dictionary contains the accepted English +spellings, as given by the International Union of Pure and Applied +Chemistry (IUPAC), of: + +- 109 named elements and their chemical symbols: hydrogen (H) to + meitnerium (Mt).
