unnilunium

provisional systematic name formed by the Interdivisional Committee on Nomenclature and Symbols (CNIC, Commission on Nomenclature of Inorganic Chemistry in English) of the IUPAC: each digit of the atomic number is translated by its Greco-Latin equivalent, attached to the others and accompanied by the suffix -ium (used to designate a chemical element). 101 is thus written using un- for 1 and nil- (derived from nihil) for zero: un-nil-un-ium '1-0-1-ium'.
