Bohrium is a metal in Group VIIB and the 7th period. It is a synthetic element; none occurs naturally on earth.

The element was discovered by Armbruster and Munzenberg at the Gesellschaft fur Schwerionenforschung at Darmstadt, Germany, in 1981. It was named for Niels Bohr, a Danish atomic and nuclear physicist.

Bh is synthetic, just as are are all other elements beyond U. It was made by bombarding 209Bi with a beam of 54Cr ions.

Little is known about the chemistry of Bohrium. It is expected to have properties similar to Rhenium.
