Dubnium was reportedly first discovered in 1968 at the Joint Institute for Nuclear Research at Dubna.

Researchers there bombarded an americium-243 target with neon-22 ions.

In the same year, a team led by Albert Ghiorso working at the University of California, Berkeley conclusively synthesized the element by bombarding a californium-249 target with nitrogen-15 ions. Named after the Russian town of Dubna 7 1772 Daniel Rutherford Scotland From the Greek words "nitron genes" meaning "nitre" and "forming" and the Latin word "nitrum"
