Being a reactive metal thorium can react with the majority of nonmetals; thorium can also form many alloys.
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.
Thorium is not soluble in water but can react slowly with water; thorium can be dissolved in hydrochloric acid or concentrated nitric acid.
Thorium (as a metal) doesn't react with hydrogen peroxide.
Thorium can react with the majority of the other nonmetals.
Thorium primarily forms compounds with elements such as oxygen, fluorine, sulfur, and carbon. It can also combine with other elements such as nitrogen, phosphorus, and various metals to form a wide range of thorium compounds.
When thorium and barium are combined, they do not react to form a specific compound. Thorium and barium are both elements and would simply mix together physically without undergoing a chemical reaction.
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 can be combined with uranium to create nuclear fuel used in certain types of nuclear reactors, such as thorium-based reactors. This combination can enhance the sustainability and safety of nuclear power generation.

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.
Beryllium is the only alkaline metal that reacts to oxygen but not to water. The hydrogen in water stabilizes the reaction.
