What does uranium react with?
Uranium makes a new substance with 10 other elements and chemicals in our lab:
- Uranium + HydrogenUranium hydride 2U + 3H₂ → 2UH₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + CarbonUranium carbide U + C → UC · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + NitrogenUranium nitride 2U + N₂ → 2UN · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + OxygenUranium dioxide U + O₂ → UO₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + SulfurUranium(IV) sulfide U + 2S → US₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + ChlorineUranium(IV) chloride U + 2Cl₂ → UCl₄ · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + BromineUranium(IV) bromide U + 2Br₂ → UBr₄ · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + IodineUranium(III) iodide 2U + 3I₂ → 2UI₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + WaterUranium dioxide + hydrogen gas U + 2H₂O → UO₂ + 2H₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Uranium + Hydrochloric AcidUranium(IV) chloride + hydrogen gas U + 4HCl → UCl₄ + 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 14 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
