Atomic number:105 ... Dubnium was discovered by workers at the Nuclear Institute at Dubna (RU) and by workers at the University of California, Berkeley (US) in 1967. The origin of the name dubnium is the Joint Nuclear Institute at Dubna, Russia, an institute heavily involved in the search for heavy elements.
