23.02.2011 | Bohrium celebrating a milestone birthday! - 30 years ago element 107 was discovered
A team of scientists headed by Professor Gottfried Münzenberg and Professor Peter Armbruster detected element 107 in Darmstadt, 30 years on February 24, 1981.
Bohrium was produced by nuclear fusion by firing chromium ions onto a bismuth foil. The element breaks down after a split second and can only be detected with very sensitive methods of analysis.
Element 107 was given the name of the Danish physicist and Nobel Prize winner Niels Bohr (1885-1962). Therefore, it should also be named Nielsbohrium at first, but in 1994 the IUPAC decided that Bohrium is its official denomination.
