IUPAC (The International Union of Pure and Applied Chemistry) has been careful about offending anyone and in the 70's suggested neutral numeric names: 104 Unq (unnilquadium), 105 Unp (unnilpentium), 106 Unh (unnilhexium), 107 Uns (unnilseptium), 108 Uno (unnioctium), 109 Une (unnilennium), and 110 (unununium).
