What does ruthenium react with?
Ruthenium makes a new substance with 4 other elements and chemicals in our lab:
- Ruthenium + OxygenRuthenium(IV) oxide Ru + O₂ → RuO₂ · When heated · Try it
- Ruthenium + FluorineRuthenium(V) fluoride 2Ru + 5F₂ → 2RuF₅ · At room temperature · Try it
- Ruthenium + SulfurRuthenium(IV) sulfide Ru + 2S → RuS₂ · When heated · Try it
- Ruthenium + ChlorineRuthenium(III) chloride 2Ru + 3Cl₂ → 2RuCl₃ · 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 21 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
