Similar to uranium, thorium can be used as a fuel in a nuclear reactor and is a key factor in the sustainability of nuclear energy. Much of the earth’s heat is attributed to the decay of both uranium and thorium. When exposed to air, the element retains a silverish whi...
ELEMENT 90 of the Periodic Table, thorium, ordinarily appears as the first element of the actinide series, appended below cerium at the bottom of Table 1. This construction gives the impression that thorium is the second member of a series starting with actinium in the scandium group, just as...

It seems I guessed right about the correct method for shipping thorium, because these people certainly know what they are doing. I chose this sample to represent its element in myPhotographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which yo...
thorium (Th), radioactive chemical element of the actinoid series of the periodic table, atomic number 90; it is a useful nuclear reactor fuel. Thorium was discovered (1828) by Swedish chemist Jöns Jacob Berzelius. It is silvery white but turns gray or black on exposure to air. It is...
