Seaborgium is the one hundred six element with the symbol Sg on the periodic table. It is a synthetic element which means that Seaborgium isn't presented in the environment at all.<ref>Winter, M.

In June 1974, scientists reported the discovery of the 106th element at the Joint Institute for Nuclear research in Dubna, USSR. Then, in September 1974, a team of scientists led by Albert Ghiorso in the Berkeley/Livermore collaboration. produced the Seaborgium by bombarding 249Cf with ions of 18O using a Super-Heavy Ion Linear Accelerator. This lead to the makings of Seaborgium and its four free neutrons. The collaboration decided to name the element in honor of American Chemist Glenn T. Seaborg, who discovered other actinides in the periodic table.<ref>Seaborgium - Wikipedia, the free encyclopedia. (n.d.).
