What does erbium react with?
Erbium makes a new substance with 10 other elements and chemicals in our lab:
- Erbium + HydrogenErbium hydride Er + H₂ → ErH₂ · When heated · Try it
- Erbium + NitrogenErbium nitride 2Er + N₂ → 2ErN · Only when heated very strongly · Try it
- Erbium + OxygenErbium oxide 4Er + 3O₂ → 2Er₂O₃ · When heated · Try it
- Erbium + FluorineErbium fluoride 2Er + 3F₂ → 2ErF₃ · At room temperature · Try it
- Erbium + SulfurErbium sulfide 2Er + 3S → Er₂S₃ · When heated · Try it
- Erbium + ChlorineErbium chloride 2Er + 3Cl₂ → 2ErCl₃ · When heated · Try it
- Erbium + BromineErbium bromide 2Er + 3Br₂ → 2ErBr₃ · When heated · Try it
- Erbium + IodineErbium iodide 2Er + 3I₂ → 2ErI₃ · When heated · Try it
- Erbium + WaterErbium hydroxide + hydrogen gas 2Er + 6H₂O → 2Er(OH)₃ + 3H₂ · At room temperature · Try it
- Erbium + Hydrochloric AcidErbium chloride + hydrogen gas 2Er + 6HCl → 2ErCl₃ + 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 15 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
