Opponents
The two principal groups which were involved in the conflict over element naming were:
- An American group at Lawrence Berkeley Laboratory.
- A Russian group at Joint Institute for Nuclear Research in Dubna.
and, as a kind of arbiter,
- The IUPAC Commission on Nomenclature of Inorganic Chemistry, which introduced its own proposal to the IUPAC General Assembly.
The German group at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, who had (undisputedly) discovered elements 107 to 109, were dragged into the controversy when the Commission suggested that the name "hahnium", proposed for element 105 by the Americans, be used for GSI's element 108 instead.
| Group | Atomic number | Name | Eponym |

| 105 | hahnium | Otto Hahn | |
| 106 | seaborgium | Glenn T. Seaborg | |

Famous quotes containing the word opponents:
“I am making a collection of the things my opponents have found me to be and, when this election is over, I am going to open a museum and put them on display.”
—Lyndon Baines Johnson (1908–1973)
“The opposition is indispensable. A good statesman, like any other sensible human being, always learns more from his opponents than from his fervent supporters. For his supporters will push him to disaster unless his opponents show him where the dangers are. So if he is wise he will often pray to be delivered from his friends, because they will ruin him. But though it hurts, he ought also to pray never to be left without opponents; for they keep him on the path of reason and good sense.”
—Walter Lippmann (1889–1974)
“The art of leadership ... consists in consolidating the attention of the people against a single adversary and taking care that nothing will split up that attention.... The leader of genius must have the ability to make different opponents appear as if they belonged to one category.”
—Adolf Hitler (1889–1945)
