What does europium react with?
Europium makes a new substance with 12 other elements and chemicals in our lab:
- Europium + HydrogenEuropium hydride Eu + H₂ → EuH₂ · When heated · Try it
- Europium + NitrogenEuropium nitride 2Eu + N₂ → 2EuN · Only when heated very strongly · Try it
- Europium + OxygenEuropium(III) oxide 4Eu + 3O₂ → 2Eu₂O₃ · When heated · Try it
- Europium + FluorineEuropium(III) fluoride 2Eu + 3F₂ → 2EuF₃ · At room temperature · Try it
- Europium + SulfurEuropium(II) sulfide Eu + S → EuS · When heated · Try it
- Europium + ChlorineEuropium(III) chloride 2Eu + 3Cl₂ → 2EuCl₃ · At room temperature · Try it
- Europium + SeleniumEuropium(II) selenide Eu + Se → EuSe · When heated · Try it
- Europium + BromineEuropium(III) bromide 2Eu + 3Br₂ → 2EuBr₃ · At room temperature · Try it
- Europium + TelluriumEuropium(II) telluride Eu + Te → EuTe · When heated · Try it
- Europium + IodineEuropium(II) iodide Eu + I₂ → EuI₂ · At room temperature · Try it
- Europium + WaterEuropium(II) hydroxide + hydrogen gas Eu + 2H₂O → Eu(OH)₂ + H₂ · At room temperature · Try it
- Europium + Hydrochloric AcidEuropium(III) chloride + hydrogen gas 2Eu + 6HCl → 2EuCl₃ + 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 13 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
