Bohrium, with the chemical symbol Bh and atomic number 107, is an artificially produced chemical element that was first synthesized in 1981 at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany. The discovery is credited to the research of Peter Armbruster, Gottfried Münzenberg, and their teams. Bohrium was created through the fusion of bismuth-209 with chromium-54 nuclei.

The name "Bohrium" was chosen to honor the Danish physicist Niels Bohr, who made significant contributions to the development of the atomic model. The discovery of Bohrium contributed to the exploration of the heaviest elements in the periodic table. Bohrium is extremely rare on Earth and does not occur naturally. It is artificially produced in particle accelerators and has limited applications, mainly in the research of the chemical properties of transuranic elements.

The key Bohrium isotopes are Bohrium-267 and Bohrium-270. Bohrium-267 has a half-life of about 17 seconds, while Bohrium-270 is approximately 22 seconds.
