It was discovered in 1828 by the Swedish chemist Jons Jakob Berzelius and named after Thor, the Norse god of thunder. In nature, virtually all thorium is found as thorium-232, which undergoes alpha decay with a half-life of about 14.05 billion years. The element has no known biological role. [Wikipedia]. Thorium is found in many foods, some of which are cashew nut, almond, black walnut, and butternut.ThThorium-232Th232.0381232.03805036thoriumthorium7440-29-1[Th]InChI=1S/ThZSLUVFAKFWKJRC-UHFFFAOYSA-N belongs to the class of inorganic compounds known as homogeneous actinide compounds.
