Is Sg a transuranium element?

Seaborgium is a transuranium element. It is created by bombarding californium-249 with oxygen-18 nuclei.

Is Sg a metal nonmetal or metalloid?

The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids. When elements combine to form compounds, there are two major types of bonding that can result….Metals, Metalloids, and Nonmetals.
