Bohrium is a synthetic element that was created in 1981 by German scientists Peter Armbruster and Gottfried M├╝nzenber. Soviet scientists had synthesized an isotope of bohrium in 1976. Bohrium was named after physicist Niels Bohr, and its original proposed name was Nielsbohrium (symbol Ns).

Bohrium (abbreviated Bh) does not exist in nature, but it is presumed to be a solid at room temperature and to have a metallic and silver-white appearance.

Because bohrium does not exist in nature, it has no commercial or scientific uses.

Bohrium
pronounced 'bôr-E-&m
Atomic Symbol Bh

Atomic Weight 264.
presumably a solid at 298 K
Color unknown, but probably metallic and silvery white or grey in appearance

Bohrium is a synthetic element that is not present in the environment. Isolation of an observable quantity of bohrium has never been achieved, and thus bohrium has no known uses. The reactivity of bohrium is unknown, but is assumed to be similar to rhenium and technetium.

Bohrium was first synthesized in 1976 at the Joint Institute for Nuclear Research at Dubna, USSR, via
Bismuth(209) + Chromium(54) = Bohrium(261) + 2 neutrons

Bohrium was also synthesized in 1981 by the Gesellschaft für Schwerionenforschung a.k.a the Institute for Heavy Ion Research a.k.a. GSI in Darmstadt, Germany, via
Lead(209) + Chromium(54) = Bohrium(262) + 1 neutron
or maybe
Bismuth(209) + Chromium(54) = Bohrium(262) + 1 neutron

Also synthesized at the Paul Scherrer Institute (PSI) in Switzerland, via
Berkelium(249) + Neon(22) = Bohrium(266) + 5 neutrons
Berkelium(249) + Neon(22) = Bohrium(267) + 4 neutrons

Element 107 was officially named bohrium in 1997; named for Niels Bohr, the Danish physicist.
