The names for the chemical elements 104 to 108 have been the subject of a major controversy starting in the 1960's which was only finally resolved in 1997. The issue is that by convention an element was named by its discoverers which led to controversy when multiple groups claimed discovery simulatenously. The three groups which conflicted over elemental naming were an American group in Berkeley, a Russian group at Dubna, and a German group.
The names preferred by the Americans were
104 - rutherfordium 105 - hahnium 106 - seaborgium
The names preferred by the Russians were
104 - kurchatovium 105 - neilsbohrium
In 1994, the IUPAC proposed the following names
104 - dubnium 105 - joliotiumm 106 - rutherfordium 107 - bohrium 108 - hahnium 109 - meitnerium
This was objected to by the American Chemical Society.
Finally in 1997, the following names were agreed to
104 - rutherfordium 105 - dubnium 106 - seaborgium 107 - bohrium 108 - hassium 109 - meitnerium
