What does samarium react with?

Samarium makes a new substance with 13 other elements and chemicals in our lab:

  • Samarium + HydrogenSamarium hydride Sm + H₂ → SmH₂ · When heated · Try it
  • Samarium + BoronSamarium boride Sm + 6B → SmB₆ · Only in a very hot furnace · Try it
  • Samarium + NitrogenSamarium nitride 2Sm + N₂ → 2SmN · Only when heated very strongly · Try it
  • Samarium + OxygenSamarium(III) oxide 4Sm + 3O₂ → 2Sm₂O₃ · When heated · Try it
  • Samarium + FluorineSamarium(III) fluoride 2Sm + 3F₂ → 2SmF₃ · At room temperature · Try it
  • Samarium + SulfurSamarium(III) sulfide 2Sm + 3S → Sm₂S₃ · When heated · Try it
  • Samarium + ChlorineSamarium(III) chloride 2Sm + 3Cl₂ → 2SmCl₃ · When heated · Try it
  • Samarium + SeleniumSamarium(III) selenide 2Sm + 3Se → Sm₂Se₃ · When heated · Try it
  • Samarium + BromineSamarium(III) bromide 2Sm + 3Br₂ → 2SmBr₃ · When heated · Try it
  • Samarium + TelluriumSamarium(III) telluride 2Sm + 3Te → Sm₂Te₃ · When heated · Try it
  • Samarium + IodineSamarium(III) iodide 2Sm + 3I₂ → 2SmI₃ · When heated · Try it
  • Samarium + WaterSamarium(III) hydroxide + hydrogen gas 2Sm + 6H₂O → 2Sm(OH)₃ + 3H₂ · At room temperature · Try it
  • Samarium + Hydrochloric AcidSamarium(III) chloride + hydrogen gas 2Sm + 6HCl → 2SmCl₃ + 3H₂ · At room temperature · 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 12 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
