This name was extremely controversial because Seaborg was still alive. An international committee decided in 1992 that the Berkeley and Dubna laboratories should share credit for the discovery. An element naming controversy erupted and as a result IUPAC adopted unnilhexium (Unh) as a temporary systematic element name.
By convention, naming rights for newly discovered chemical elements go to their discoverers. For elements 104, 105, and 106, there was a controversy between Soviet researchers at the Joint Institute for Nuclear Research and American researchers at Lawrence Berkeley National Laboratory regarding which group had discovered them first.
The naming of the synthetic elements dubnium and seaborgium generated a significant amount of controversy, referred to as the Transfermium Wars. The Americans wished to name element 105 hahnium, while the Russians preferred the name dubnium. The Americans also wished to name element 106 seaborgium.
[65] [66] When LBL first announced their synthesis of element 105, they proposed that the new element be named hahnium (Ha) after the German chemist Otto Hahn, the "father of nuclear chemistry", thus creating an element naming controversy. [67]
As a consequence of the initial competing claims of discovery, an element naming controversy arose. Since the Soviets claimed to have first detected the new element they suggested the name kurchatovium (Ku) in honor of Igor Kurchatov (1903–1960), former head of Soviet nuclear research.

Each team proposed its own name for element 110: the American team proposed hahnium after Otto Hahn in an attempt to resolve the controversy of naming element 105 (which they had long been suggesting this name for), the Russian team proposed becquerelium after Henri Becquerel, and the German team proposed darmstadtium after Darmstadt, the ...
The naming of meitnerium was discussed in the element naming controversy regarding the names of elements 104 to 109, but meitnerium was the only proposal and thus was never disputed.
