[edit]

Bohrium is a synthetic chemical element with the symbol Bh and atomic number 107. It is named after Danish physicist Niels Bohr. As a synthetic element, it can be created in a laboratory but is not found in nature. All known isotopes of bohrium are highly radioactive; the most stable known isotope is 270Bh with a half-life of approximately 61 seconds, though the unconfirmed 278Bh may have a longer half-life of about 690 seconds.

In the periodic table, it is a d-block transactinide element. It is a member of the 7th period and belongs to the group 7 elements as the fifth member of the 6d series of transition metals. Chemistry experiments have confirmed that bohrium behaves as the heavier homologue to rhenium in group 7. The chemical properties of bohrium are characterized only partly, but they compare well with the chemistry of the other group 7 elements.

Bohrium is a chemical element with the symbol Bh and the atomic number 107. Bohrium is highly radioactive; its most stable known isotopes have half-lives of approximately a minute. Bohrium is a superheavy element; it has been produced in a laboratory only in very small quantities by fusing heavy nuclei with lighter ones.

In the periodic table of elements, bohrium is a transactinide element, a member of the 7th period and group 7; it is thus the fifth member of the 6d series of transition metals. Chemistry experiments have confirmed that hassium behaves as the heavier homologue to rhenium in group 7. The chemical properties of bohrium have been only partly characterized, but they compare well with the chemistry of the other group 7 elements.
