State: Solid Transition Metals
106 106 163 Discovery: 1974

Atoms of seaborgium break apart in about
three minutes, so little is known about it.
Scientists think it may be a metal. The element
was isolated in 1974 in a machine called the
Super Heavy Ion Linear Accelerator at the
Lawrence Berkeley National Laboratory. It was
named after the US scientist Glenn T Seaborg.

machine in which atoms
are smashed together. Glenn T Seaborg

NOBEL PRIZE IN CHEMISTRY

Glenn T Seaborg and his fellow US researcher
Edwin McMillan were awarded the Nobel
Prize for Chemistry in 1951 for their work
in creating neptunium. This was the first
element to be isolated that was heavier than
uranium – the heaviest natural element.
