Bohrium is named after Niels Bohr, the Danish physicist. Its chemical properties are predicted to be similar to rhenium.

About Bohrium

Predictions for bohrium's chemistry lean on its position in group 7 of period 7, immediately below rhenium, and experiments so far are consistent with that expectation. The element is named for Niels Bohr, whose model of the atom first tied electron arrangement to chemical periodicity. Bohrium carries atomic number 107, a relative atomic mass of 270.0, and the configuration [Rn] 5f14 6d5 7s2. No electronegativity value has been determined. Like all transactinides it is synthetic and short-lived, made in accelerators and identified from its decay chain; chemical information comes from gas-phase separations that must be completed within seconds of an atom being formed.
