What does tantalum react with?
Tantalum makes a new substance with 9 other elements and chemicals in our lab:
- Tantalum + BoronTantalum boride Ta + 2B → TaB₂ · Only in a very hot furnace · Try it
- Tantalum + CarbonTantalum carbide Ta + C → TaC · Only in a very hot furnace · Try it
- Tantalum + NitrogenTantalum nitride 2Ta + N₂ → 2TaN · Only when heated very strongly · Try it
- Tantalum + OxygenTantalum oxide 4Ta + 5O₂ → 2Ta₂O₅ · When heated · Try it
- Tantalum + FluorineTantalum fluoride 2Ta + 5F₂ → 2TaF₅ · At room temperature · Try it
- Tantalum + SulfurTantalum sulfide Ta + 2S → TaS₂ · When heated · Try it
- Tantalum + ChlorineTantalum chloride 2Ta + 5Cl₂ → 2TaCl₅ · When heated · Try it
- Tantalum + BromineTantalum bromide 2Ta + 5Br₂ → 2TaBr₅ · When heated · Try it
- Tantalum + IodineTantalum iodide 2Ta + 5I₂ → 2TaI₅ · When heated · 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 16 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
