seaborgium
Also known as Sg, element 106, unnilhexium, Unh
Seaborgium is a synthetic chemical element; it has symbol Sg and atomic number 106. It is named after the American nuclear chemist Glenn T. Seaborg. As a synthetic element, it can be created in a laboratory but is not found in nature. It is also radioactive; the most stable known isotopes have half-lives on the order of several minutes.
AI overview
Seaborgium is a human-made radioactive element (symbol Sg, atomic number 106) that can only be created in laboratories and breaks down quickly, with its most stable forms lasting just minutes. It was named after American nuclear chemist Glenn T. Seaborg and represents one of the heaviest elements on the periodic table that scientists have been able to synthesize.

Seaborgium is a synthetic chemical element; it has symbol Sg and atomic number 106. It is named after the American nuclear chemist Glenn T. Seaborg. As a synthetic element, it can be created in a laboratory but is not found in nature. It is also radioactive; the most stable known isotopes have half-lives on the order of several minutes.
In the periodic table of the elements, it is a d-block transactinide element. It is a member of the 7th period and belongs to the group 6 elements as the fourth member of the 6d series of transition metals. Chemistry experiments have confirmed that seaborgium behaves as the heavier homologue to tungsten in group 6. The chemical properties of seaborgium are characterized only partly, but they compare well with the chemistry of the other group 6 elements.
