Seaborgium is used only for research and has no practical or biological use. It is a radioactive, transuranium, man-made element whose atomic number is 106. Its melting point, boiling point and density are unknown.Continue Reading
Seaborgium is the result of an isotope of californium being bombarded with oxygen ions. Only a few atoms of seaborgium have been created. Scientists believe it is a transition metal that is solid at room temperature.
Seaborgium's most stable isotope has a half-life of about two minutes. Most of its other isotopes have half-lives of less than a second. Scientists believe that another isotope of seaborgium has been discovered whose half-life is a bit over two minutes, but this was deduced from observing the decay of a single atom.
The element was discovered at the Lawrence Berkeley Laboratory and the Livermore National Laboratory, both in the United States. It was named after Nobel prize winning nuclear chemist Glenn Seaborg. Like many transuranium elements, seaborgium was created in a particle accelerator. The scientists who discovered seaborgium in September, 1974, were Albert Ghiorso and E. Kenneth Hulet.
A team at the Joint Institute for Nuclear Research in what was then the Soviet Union also claimed to have discovered element 106 in June, 1974.Learn more about Chemistry
