What does thorium react with?
Thorium makes a new substance with 10 other elements and chemicals in our lab:
- Thorium + HydrogenThorium hydride Th + H₂ → ThH₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + CarbonThorium carbide Th + 2C → ThC₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + NitrogenThorium nitride 2Th + N₂ → 2ThN · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + OxygenThorium oxide Th + O₂ → ThO₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + FluorineThorium fluoride Th + 2F₂ → ThF₄ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + SulfurThorium sulfide Th + 2S → ThS₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + ChlorineThorium chloride Th + 2Cl₂ → ThCl₄ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + BromineThorium bromide Th + 2Br₂ → ThBr₄ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + IodineThorium iodide Th + 2I₂ → ThI₄ · Only in a special nuclear lab (it is radioactive) · Try it
- Thorium + Hydrochloric AcidThorium chloride + hydrogen gas Th + 4HCl → ThCl₄ + 2H₂ · Only in a special nuclear lab (it is radioactive) · Try it
It also blends into a mixture, like an alloy, with 73 other metals when melted together.
Nothing happens when it's simply mixed with 15 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
