Bohrium was synthesized in 1981 at GSI Darmstadt by a team led by Peter Armbruster and Gottfried Münzenberg. It was named after Niels Bohr.
Bohrium-270
Half-life: About 1-4 minutes. Among the longer-lived known bohrium isotopes; reported values vary by nuclear data source and state.Bohrium-274
Half-life: About 44-57 seconds. Observed in decay chains of heavier superheavy elements.BhO₃Cl

Bohrium has no biological role. It is synthetic, radioactive and exists only as short-lived atoms.
- Bohrium chemistry experiments support its behavior as a heavier homolog of rhenium.
- Only a handful of bohrium atoms are needed in experiments that test Group 7 chemistry.
- The element name honors Niels Bohr’s role in atomic structure and nuclear physics.
- Bohrium has atomic number 107 and symbol Bh.
- Its listed electron configuration is [Rn] 5f¹⁴ 6d⁵ 7s²; superheavy element values are partly prediction-based.
- Bohrium is a Group 7 transactinide below rhenium.
- Remember BhO₃Cl for gas-phase chemistry evidence.
What is the atomic number of bohrium?
