Sg
Seaborgium/Symbol
Seaborgium (Sg), an artificially produced radioactive element in Group VIb of the periodic table, atomic number 106. In June 1974, Georgy N. Flerov of the Joint Institute for Nuclear Research at Dubna, Russia, U.S.S.R. , announced that his team of investigators had synthesized and identified element 106.

What is Db in element?

Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. The element was formally named dubnium in 1997 after the town of Dubna, the site of the JINR.

Where can dubnium be found?

Named after Dubna, the area near Moscow where Soviet scientists discovered rutherfordium and dubnium. Dubnium is a highly radioactive metal. It has never been found naturally and only a small number of atoms have been produced in laboratories.

What makes dubnium unique?

Properties of dubnium Dubnium has seven recognized isotopes. The most stable is 268Db, which has a half-life of about 32 hours. It decays through spontaneous fission. For naturally occurring elements, the atomic weight is calculated from averaging the weights of the natural abundances of the isotopes of that element.
