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.
The names for the chemical elements 104 to 106 were the subject of a major controversy starting in the 1960s, described by some nuclear chemists as the Transfermium Wars [1] [2] because it concerned the elements following fermium (element 100) on the periodic table.
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.
The International Union of Pure and Applied Chemistry adopted unnilquadium (Unq) as a temporary, systematic element name, derived from the Latin names for digits 1, 0, and 4. In 1994, IUPAC suggested a set of names for elements 104 through 109, in which dubnium (Db) became element 104 and rutherfordium became element 106. [59]

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 ...

In 1994, as part of an attempted resolution to the element naming controversy, IUPAC ratified names for elements 101–109. For element 102, it ratified the name nobelium (No) on the basis that it had become entrenched in the literature over the course of 30 years and that Alfred Nobel should be commemorated in this fashion.
