Thorium is an inner transition metal in the actinide series. It follows actinium in period seven of the periodic table. When pure, thorium is a silvery white metal that retains its luster for several months. However, when it is contaminated with the oxide, thorium slowly tarnishes in air, becoming gray and eventually black.
