bohrium
Definition
Bohrium is a chemical element with the symbol Bh and atomic number 107. It is a synthetic element, meaning that it does not occur naturally. It was first synthesized in 1976 by a team of scientists at the Joint Institute for Nuclear Research in Dubna, Russia.
Bohrium is a heavy metal that is radioactive. It has a half-life of about 270 milliseconds, which means that it takes 270 milliseconds for half of a sample of bohrium to decay.
Bohrium is named after Niels Bohr, a Danish physicist who made important contributions to our understanding of the atom.
Bohrium is a member of the transactinide series, which is a group of elements that are heavier than uranium. The transactinide series is still being explored, and scientists are learning more about bohrium and other elements in this series all the time.
