IUPAC accepted the name proposed by the international discovering team around Sigurd Hofmann at the GSI Helmholtzzentrum. The team had suggested 'Cp' as the chemical symbol for the new element. However, since the chemical symbol 'Cp' gave cause for concerns, as this abbreviation also has other scientific meanings, the discoverers and IUPAC agreed to change the symbol to 'Cn.' Copernicium is 277 times heavier than hydrogen, making it the heaviest element officially recognised by IUPAC...
