Bohrium
Bohrium is a synthetic element with the symbol Bh and atomic number 107. It was discovered in 1976 by a team led by Peter Armbruster and Gottfried Münzenberg at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany.
Bohrium is a member of the 7th period and the 3rd group of the periodic table and is solid metal. It is predicted to be a noble gas-like element, with a very stable electron configuration. Bohrium is predicted to be a very heavy metal, with a density of around 22.5 g/cm3. It is expected to have a boiling point of around 5,000 K, and a melting point of around 1,700 K.
Bohrium is a synthetic chemical element with the symbol Bh and atomic number 107. It is a radioactive metal that has only been created in the laboratory and has no stable isotopes.
Bohrium was first created in 1976 by a team of German scientists led by Peter Armbruster and Gottfried Münzenberg. They bombarded a target of bismuth with accelerated nuclei of chromium to create bohrium atoms.
Bohrium is a member of the group 7 elements, the transition metals. It is a silver-white metal that is very brittle and slowly oxidizes in the air. It is a very dense metal, similar in density to lead.
Bohrium is not found naturally on Earth, but it is expected to be found in the cosmos as a result of supernovae.
Properties
Bohrium is a synthetic chemical element with the symbol Bh and atomic number 107. It is a radioactive metal that has only been created in laboratories. Bohrium is the heaviest member of the group 7 elements (the halogens), and it is the most radioactive member of that group.
Bohrium has no known uses, but it is possible that it could be used in radiation therapy or in nuclear weapons. The primary source of bohrium is the nuclear reaction between berkelium-249 and calcium-48.
Bohrium is a very radioactive metal. It has a half-life of only about 10.5 days, which means that it will radioactively decay by half in that time. This makes it very difficult to study and use in any practical way.
