[Latinized from Thor (q. v.).] Chem.: Thorium. Atomic weight=1157; symbol Th. A divalent metallic element belonging to the group of earth-metals discovered by Berzelius, in 1828, in thorite. It is a very rare element, and is pota ium. The reduced thorinum is a gray mh obtained by heating chloride with tallic powder, having a specific gravity of 7-65-7-79. When heated, it burns with a bright flame, produc ing snow-white thorina without any trace of fusion. It is not oxidized by either hot or cold water, di olves slowly in nitric and sulphuric acids, more easily in hydrochloric acid, and is not attacked by caustic alkalies. thorinum-chloride, s.

Obtained as a gelatinous ma by the action of caustic alkalies on solutions of thorinum salts. Under the air pump it dries up into a white powder, readily soluble in all acids, except ing oxalic, molybdic, and hydrofluoric acids. thorinum-oxide, s. [THORINA.] thorinum-sulphide, s. I.
