How do you make seaborgium?
Seaborgium was first produced by a team of scientists led by Albert Ghiorso working at the Lawrence Berkeley Laboratory in Berkeley, California, in 1974. They created seaborgium by bombarding atoms of californium-249 with ions of oxygen-18 using a machine called the Super-Heavy Ion Linear Accelerator.
What is seaborgium element family?
The chemical symbol will be Sg. Seaborgium is in the family of “transuranium” elements — those beyond uranium on the periodic table. Uranium, element 92, is the heaviest known naturally occurring element. The transuranium elements can be artificially created in particle accelerators.
