Thorium is a chemical element with symbol Th and atomic number 90. A radioactive actinide metal thorium is one of only two significantly radioactive elements that still occur naturally in large quantities as a primordial element (the other being uranium). It was discovered in 1829 by the Norwegian amateur mineralogist Morten Thrane Esmark and identified by the Swedish chemist Jöns Jacob Berzelius who named it after Thor the Norse god of thunder.
