What does indium react with?

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

  • Indium + OxygenIndium oxide 4In + 3O₂ → 2In₂O₃ · When heated · Try it
  • Indium + FluorineIndium fluoride 2In + 3F₂ → 2InF₃ · At room temperature · Try it
  • Indium + PhosphorusIndium phosphide In + P → InP · When heated · Try it
  • Indium + SulfurIndium sulfide 2In + 3S → In₂S₃ · When heated · Try it
  • Indium + ChlorineIndium chloride 2In + 3Cl₂ → 2InCl₃ · When heated · Try it
  • Indium + ArsenicIndium arsenide In + As → InAs · When heated · Try it
  • Indium + SeleniumIndium selenide 2In + 3Se → In₂Se₃ · When heated · Try it
  • Indium + BromineIndium bromide 2In + 3Br₂ → 2InBr₃ · When heated · Try it
  • Indium + TelluriumIndium telluride 2In + 3Te → In₂Te₃ · When heated · Try it
  • Indium + IodineIndium iodide 2In + 3I₂ → 2InI₃ · When heated · Try it
  • Indium + Hydrochloric AcidIndium chloride + hydrogen gas 2In + 6HCl → 2InCl₃ + 3H₂ · At room temperature · Try it

It also blends into a mixture, like an alloy, with 74 other metals when melted together.

Nothing happens when it's simply mixed with 13 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
