What does curium react with?

Curium makes a new substance with 6 other elements and chemicals in our lab:

  • Curium + OxygenCurium oxide 4Cm + 3O₂ → 2Cm₂O₃ · Only in a special nuclear lab (it is radioactive) · Try it
  • Curium + FluorineCurium fluoride 2Cm + 3F₂ → 2CmF₃ · Only in a special nuclear lab (it is radioactive) · Try it
  • Curium + ChlorineCurium chloride 2Cm + 3Cl₂ → 2CmCl₃ · Only in a special nuclear lab (it is radioactive) · Try it
  • Curium + BromineCurium bromide 2Cm + 3Br₂ → 2CmBr₃ · Only in a special nuclear lab (it is radioactive) · Try it
  • Curium + IodineCurium iodide 2Cm + 3I₂ → 2CmI₃ · Only in a special nuclear lab (it is radioactive) · Try it
  • Curium + Hydrochloric AcidCurium chloride + hydrogen gas 2Cm + 6HCl → 2CmCl₃ + 3H₂ · 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 19 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
