Etymology

Origin of seaborgium

First recorded in 1965–70; officially assigned to element 106 in 1997; named after U.S. chemist Glenn T. Seaborg; -ium ( def. )

Example Sentences

And by carrying seaborgium quickly to a reaction chamber so that its compounds can be produced and separated by both gas and liquid chromatography, chemists proved two decades ago that this is true1,2.

From Nature

The first was element 106, seaborgium, named for Glenn T. Seaborg.

From New York Times

The first such occasion led to huge controversy, when in 1993 a team at the Lawrence Berkeley National Laboratory proposed naming element 106 seaborgium for US nuclear-chemistry pioneer Glenn Seaborg.

From Nature

Over the course of 30 years, his inventions contributed to the discovery of americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, rutherfordium, dubnium and seaborgium.

From New York Times

Glenn Seaborg was immortalised in his lifetime by element 106, seaborgium, which he considered a far greater honour than the Nobel Prize he won along with McMillan in 1951.
