描述 • 用途/功能

On December 20, 1994, scientists at GSI Darmstadt, Germany announced they had detected three atoms of a new element with 111 protons and 161 neutrons. This element was made by bombarding bismuth-83 with nickel-28. Signals of Element 111 appeared for less than 0.002 sec, then decayed into lighter elements including Element 109-268 and Element 107-264. These isotopes had not previously been observed. A name for Element 111 has not been suggested although IUPAC has suggested a temporary name of Unununium. 1
