 The first experiment allowed detection of three atoms of 283Cn but also seemingly detected 1 atom of 287Fl . This result was a surprise given the transport time of the product atoms is ~ 2 s , so the flerovium atoms produced should have decayed to copernicium before adsorption . In the second reaction , 2 atoms of 288Fl and possibly 1 atom of 289Fl were detected . Two of the three atoms displayed adsorption characteristics associated with a volatile , noble @-@ gas @-@ like element , which has been suggested but is not predicted by more recent calculations . These experiments provided independent confirmation for the discovery of copernicium , flerovium , and livermorium via comparison with published decay data . Further experiments in 2008 to confirm this important result detected a single atom of 289Fl , and supported previous data showing flerovium having a noble @-@ gas @-@ like interaction with gold .
