What does rubidium react with?
Rubidium makes a new substance with 11 other elements and chemicals in our lab:
- Rubidium + HydrogenRubidium hydride 2Rb + H₂ → 2RbH · When heated · Try it
- Rubidium + OxygenRubidium superoxide Rb + O₂ → RbO₂ · When heated · Try it
- Rubidium + FluorineRubidium fluoride 2Rb + F₂ → 2RbF · At room temperature · Try it
- Rubidium + SulfurRubidium sulfide 2Rb + S → Rb₂S · When heated · Try it
- Rubidium + ChlorineRubidium chloride 2Rb + Cl₂ → 2RbCl · At room temperature · Try it
- Rubidium + SeleniumRubidium selenide 2Rb + Se → Rb₂Se · When heated · Try it
- Rubidium + BromineRubidium bromide 2Rb + Br₂ → 2RbBr · At room temperature · Try it
- Rubidium + TelluriumRubidium telluride 2Rb + Te → Rb₂Te · When heated · Try it
- Rubidium + IodineRubidium iodide 2Rb + I₂ → 2RbI · At room temperature · Try it
- Rubidium + WaterRubidium hydroxide + hydrogen gas 2Rb + 2H₂O → 2RbOH + H₂ · At room temperature · Try it
- Rubidium + Hydrochloric AcidRubidium chloride + hydrogen gas 2Rb + 2HCl → 2RbCl + H₂ · At room temperature · Try it
It also blends into a mixture, like an alloy, with 74 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.
