Thorium was discovered in 1829 by the Swedish chemist Jons Jakob Berzelius.
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.

Hazards and Health Considerations: Thorium presents both a toxic and radiological hazard. Toxicologically, it causes heavy metal poisoning similar to lead or the uranium isotopes. Biologically, thorium accumulates in the skeletal system where it has a biological half-life of 200 years, the same as plutonium. An M 17 protective mask and standard anti-contamination clothing will adequately protect against thorium.

Thorium don't smell.
Thorium (Th).
Thorium-232 is appearing in the thorium series.
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
Thorium: soft but strong! Thorium is totally radioactive!
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.
