What does rhenium react with?

Rhenium makes a new substance with 5 other elements and chemicals in our lab:

  • Rhenium + OxygenRhenium(VII) oxide 4Re + 7O₂ → 2Re₂O₇ · When heated · Try it
  • Rhenium + FluorineRhenium(VI) fluoride Re + 3F₂ → ReF₆ · At room temperature · Try it
  • Rhenium + SulfurRhenium(IV) sulfide Re + 2S → ReS₂ · When heated · Try it
  • Rhenium + ChlorineRhenium(V) chloride 2Re + 5Cl₂ → 2ReCl₅ · When heated · Try it
  • Rhenium + BromineRhenium(III) bromide 2Re + 3Br₂ → 2ReBr₃ · 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 20 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
