bohrium

Also known as element 107

Bohrium is a synthetic chemical element; it has symbol Bh and atomic number 107. It is named after Danish physicist Niels Bohr. As a synthetic element, it can be created in particle accelerators 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 2.4 minutes, though the unconfirmed 278Bh may have a longer half-life of about 11.5 minutes.

AI overview

Bohrium is a human-made chemical element (symbol Bh, atomic number 107) named after physicist Niels Bohr that can only be created in particle accelerators and exists nowhere in nature. All known forms of bohrium are highly radioactive and decay very quickly—the most stable confirmed version lasts only about 2.4 minutes—which limits its practical applications and makes it primarily valuable for scientific research.

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.
