▸ The reading
interpretive · artBohrium honours the man whose 1913 atomic model explains why the table has the shape it has — and the element repays the debt by obeying it: BhO₃Cl behaves like its group-7 analogue rhenium's, exactly where Bohr's shells say it should. Theory and namesake auditing each other, one atom at a time.

▸ The lenses
▸ Discovery
Peter Armbruster + Gottfried Münzenberg + colleagues at GSI Darmstadt · Germany · 1981
▸ Stellar origin
Human-madeGroup-7 transactinide. Longest-lived isotope ²⁷⁰Bh has a half-life of about a minute.
▸ Reactivity
BhO₃Cl behaves like ReO₃Cl — group 7 confirmedGas-phase chemistry with five atoms at a time was enough to fingerprint Bh as a rhenium analogue.
▸ Applications
- Probing heavy-element chemistry at one-atom-at-a-time scale
- Heavy-element synthesis research
- (No commercial applications)
- (No practical bulk uses)
▸ Curiosity
Named for Niels Bohr — the physicist whose 1913 atomic model is what allows us to predict where elements like Bh should sit on the periodic table.
