**Discovery:** Karl Karlovich Klaus
 * Isotopes:** 96-Ru, 98-Ru,99-Ru,100-Ru,101-Ru,102-Ru,104-Ru,95-Ru,97-Ru,103-Ru,105-Ru,106-Ru
 * Name:** Ruthenium was named after the Latin word  "Ruthenia" meaning Russia.


 * Uses:** One of the most effective hardeners for platinum and palladium, and is alloyed with these metals to make electrical contacts for severe wear resistance.Corrosion resistance of titanium is improved a hundred times by addition of 0.1% ruthenium.Versatile catalyst. Hydrogen sulphide can be split catalytically by light using an aqueous suspension of CdS particles loaded with ruthenium dioxide. This may have application to removal of H2S from oil and in other industrial processes, catalysts.Hardener for platinum and palladium, alloying for corrosion resistance


 * Interesting Facts**:Ruthenium is a hard, white metal. It does not tarnish at room temperatures, but oxidises in air at about 800°C.
