What does molybdenum react with?

Molybdenum makes a new substance with 11 other elements and chemicals in our lab:

  • Molybdenum + BoronMolybdenum boride Mo + B → MoB · Only in a very hot furnace · Try it
  • Molybdenum + CarbonMolybdenum carbide 2Mo + C → Mo₂C · Only in a very hot furnace · Try it
  • Molybdenum + OxygenMolybdenum(VI) oxide 2Mo + 3O₂ → 2MoO₃ · When heated · Try it
  • Molybdenum + FluorineMolybdenum(VI) fluoride Mo + 3F₂ → MoF₆ · At room temperature · Try it
  • Molybdenum + SiliconMolybdenum silicide Mo + 2Si → MoSi₂ · Only in a very hot furnace · Try it
  • Molybdenum + SulfurMolybdenum disulfide Mo + 2S → MoS₂ · When heated · Try it
  • Molybdenum + ChlorineMolybdenum(V) chloride 2Mo + 5Cl₂ → 2MoCl₅ · When heated · Try it
  • Molybdenum + SeleniumMolybdenum(IV) selenide Mo + 2Se → MoSe₂ · When heated · Try it
  • Molybdenum + BromineMolybdenum(III) bromide 2Mo + 3Br₂ → 2MoBr₃ · When heated · Try it
  • Molybdenum + TelluriumMolybdenum(IV) telluride Mo + 2Te → MoTe₂ · When heated · Try it
  • Molybdenum + IodineMolybdenum(III) iodide 2Mo + 3I₂ → 2MoI₃ · When heated · 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.
