WebThorium is a chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure. The chemical symbol for Thorium is Th . Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. WebHe expected a difference because uranium and thorium decay into different isotopes of lead. The lead from the uranium-rich ore had an average atomic weight of 206.08 compared to 207.69 for the lead from the thorium-rich ore, thus verifying Soddy's conclusion. how many refrigerators on one 30a circuit
