This is an important and highly-visible honor which touches on national and institutional pride, and future funding.
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).
Very few researchers used these names which further confused the situation since many of these elements had more than one name to choose from.
