Thorium is a solid, natural, radioactive metal.
Common compounds of thorium: thorium dioxide, thorium trifluoride, thorium tetrafluoride, thorium tetrachloride, thorium triiodide, thorium diiodide, thorium tetraiodide, thorium nitrate, thorium oxalate, thorium carbide, thorium sulfides, thorium nitride, thorium oxinate, etc.
Thorium (Th).
Thorium is a tetravalent element. Thorium react slowly with water; thorium can react with concentrated nitric acid and hydrogen chloride. Thorium can react with the majority of other chemical elements. The Pauling electronegativity of thorium is 1,3.
Bitumen has not thorium.
Thorium can react with the majority of non metals; with metals thorium form alloys.
THORIUM
Thorium is an inner transition element, which means it is a metal.

Thorium is mainly found in India.
Thorium is extracted from minerals as monazite, thorianite, thorite, the mineral is grounded, dissolved in nitric acid, thorium is extracted with tributylphosphate. Also other methods exist.Pure thorium is obtained from ThO2 by a calciothermic process, from ThI2 by thermal decomposition or from ThF4 by electrolysis.
Radium has not its own minerals; radium exist in extremely low concentrations in uranium and thorium ores.
Thorium is not typically found in significant quantities in yellow sand. The composition of yellow sand varies, but it is typically composed of small particles of quartz, feldspar, and other minerals. Thorium is a radioactive element that is more commonly found in certain types of rocks such as monazite and thorianite.
Examples: - thorianite: oxides group - thorite: silicates group - monazite: phosphates group

Swedish chemist Jöns Jakob Berzelius analyzed a mineral from the Falun district in 1815 and determined that it contained a new element, which he named thorium after Thor, the Norse god of thunder.
These activities should not be eliminated because thorium is useful; only appropriate protection measures to be taken.
