Pure thorium is a silvery white metal that retains lustre for months. Thorium oxide has the highest melting point among all oxides. Discovered by Berzelius in 1828 in thorite mineral sample
China plans to build world's first molten salt nuclear power station in Gobi Desert. Construction to begin next year, operation expected by 2025. Uses thorium as fuel instead of uranium
Discovered by Berzelius in 1828 from thorite mineral in Norway. First element after uranium to be identified as radioactive. Isolated by reacting thorium chloride with potassium
Thorium (Th) has atomic number 90 and is found in Period 7. It is a soft, silvery-white metal with melting point of 1750°C. Pure thorium is highly reactive and can ignite in air. It has 28 radioactive isotopes, with 232Th being most stable
Discovered by Berzelius in 1828 in thorite mineral. Pure thorium is silvery-white metal with high ductility. Melting point is 1750°C, boiling point 4788°C. Makes up about 0.0007% of earth's crust
