| Reactions of Ruthenium |
 Reactions with water |
| Ruthenium does not react with water under normal conditions. |
| Reactions with air |
| Ruthenium is largely immune to atmospheric attack. On heating with oxygen, ruthenium metal gives ruthenium (IV) oxide.

Ru(s) + O2(g) RuO2(s) |
| Reactions with halogens |
| Ruthenium reacts with excess of fluorine to form ruthenium(VI) fluoride.
|
| Ru(s) + 3F2(g)RuF6(s) |
| Heating ruthenium metal at 330°C with chlorine in the presence of carbon monoxide produces dark brown ruthenium(III) chloride, RuCl3; further heating of this product under Cl2 yields a black form of ruthenium(III) chloride.
