What does scandium react with?
Scandium makes a new substance with 10 other elements and chemicals in our lab:
- Scandium + HydrogenScandium hydride Sc + H₂ → ScH₂ · When heated · Try it
- Scandium + NitrogenScandium nitride 2Sc + N₂ → 2ScN · Only when heated very strongly · Try it
- Scandium + OxygenScandium oxide 4Sc + 3O₂ → 2Sc₂O₃ · When heated · Try it
- Scandium + FluorineScandium fluoride 2Sc + 3F₂ → 2ScF₃ · At room temperature · Try it
- Scandium + SulfurScandium sulfide 2Sc + 3S → Sc₂S₃ · When heated · Try it
- Scandium + ChlorineScandium chloride 2Sc + 3Cl₂ → 2ScCl₃ · When heated · Try it
- Scandium + BromineScandium bromide 2Sc + 3Br₂ → 2ScBr₃ · When heated · Try it
- Scandium + IodineScandium iodide 2Sc + 3I₂ → 2ScI₃ · When heated · Try it
- Scandium + WaterScandium hydroxide + hydrogen gas 2Sc + 6H₂O → 2Sc(OH)₃ + 3H₂ · At room temperature · Try it
- Scandium + Hydrochloric AcidScandium chloride + hydrogen gas 2Sc + 6HCl → 2ScCl₃ + 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.
