What does holmium react with?
Holmium makes a new substance with 10 other elements and chemicals in our lab:
- Holmium + HydrogenHolmium hydride Ho + H₂ → HoH₂ · When heated · Try it
- Holmium + NitrogenHolmium nitride 2Ho + N₂ → 2HoN · Only when heated very strongly · Try it
- Holmium + OxygenHolmium oxide 4Ho + 3O₂ → 2Ho₂O₃ · When heated · Try it
- Holmium + FluorineHolmium fluoride 2Ho + 3F₂ → 2HoF₃ · At room temperature · Try it
- Holmium + SulfurHolmium sulfide 2Ho + 3S → Ho₂S₃ · When heated · Try it
- Holmium + ChlorineHolmium chloride 2Ho + 3Cl₂ → 2HoCl₃ · When heated · Try it
- Holmium + BromineHolmium bromide 2Ho + 3Br₂ → 2HoBr₃ · When heated · Try it
- Holmium + IodineHolmium iodide 2Ho + 3I₂ → 2HoI₃ · When heated · Try it
- Holmium + WaterHolmium hydroxide + hydrogen gas 2Ho + 6H₂O → 2Ho(OH)₃ + 3H₂ · At room temperature · Try it
- Holmium + Hydrochloric AcidHolmium chloride + hydrogen gas 2Ho + 6HCl → 2HoCl₃ + 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.
