Did You Know?
It is named in honor of Niels Bohr, the Danish physicist who made foundational contributions to understanding atomic structure and quantum theory.
The German team at GSI that discovered it suggested the name 'nielsbohrium', but IUPAC eventually shortened it to 'bohrium'.
Its most stable isotope has a half-life of about 61 seconds.
It is a member of Group 7 of the periodic table and is expected to have properties similar to rhenium.
