Brief Introduction
Dubnium (Db) is a synthetic, radioactive transactinide element. Key details about Dubnium (Db) are as follows:
Uses: No practical applications. Used only in scientific research to study superheavy element chemistry.
Production/Extraction: Produced by bombarding americium or californium with neon ions in particle accelerators. Only a few atoms are produced at a time.
History: Discovered independently in 1968-1970 by teams at Dubna, Russia and UC Berkeley. Named after Dubna, Russia, after a naming controversy.
Health Effects & Safety: Highly radioactive. Extreme rarity means no health data.
Price/Market: Not commercially available. Produced only for research.
Properties: Radioactive, most stable isotope Db-268 has half-life of about 28 hours, expected to behave chemically similar to tantalum.
