• For example, " Uno " was the temporary symbol for hassium ( element 108 ) which had the temporary name of " unniloctium ".
• Dropped from the union's previous list of provisional names are " joliotium " for Element 105, for the French physicist Frederick Joliot-Curie, and " hahnium " for Element 108, honoring the German physicist Otto Hahn.
• The German group at the Gesellschaft f黵 Schwerionenforschung ( GSI ) in Darmstadt, who had ( undisputedly ) discovered elements 107 to 109, were dragged into the controversy when the Commission suggested that the name " hahnium ", proposed for element 105 by the Americans, be used for GSI's element 108 instead.
• Although widely used in the chemical community on all levels, from chemistry classrooms to advanced textbooks, the recommendations were mostly ignored among scientists in the field, who either called it " element 108 ", with the symbol of " ( 108 ) " or even simply " 108 ", or used the proposed name " hassium ".
• In 1994 a committee of IUPAC recommended that element 108 be named " hahnium " ( Hn ) after the German physicist Otto Hahn, after an older suggestion of " ottohahnium " ( Oh ) so that elements named after Hahn and Lise Meitner ( meitnerium ) would be next to each other, honoring their joint discovery of nuclear fission.
