Chemical Properties:-Unreactive most of the time-Insoluble in acids-Oxidises in air at about 800°C. -No reaction to oxygen at room temperature-Oxidises explosively when potassium chlorate is added to the solution-Unaffected by air, water and acids.-Reacts with molten alkali and halogens-One of the most effective hardeners for platinum and palladium
Physical Properties:-Melting Point: 27 K (2334°C or 4233°F)-Density is12.2 grams per cubic centimeter-Melting point is 4,233°F (2,334°C)-Boiling point is 7,502°F (4,150°C)-Silvery white-Odorless-Hard-Solid at room temperatureShiny surface
History of Ruthenium:Ruthenium was isolated in 1844 by Karl Karlovich Klaus, who obtained ruthenium while analyzing the residue of a sample of platinum ore obtained from the Ural mountains.Polish chemist Jedrzej Sniadecki and Russian chemist Gottfried W. Osann had in fact isolated ruthenium from some platinum ores in the early 1800s. It is a rare hard silvery-white transition metal belonging to the platinum group of the periodic table.

Fun Facts-Ruthenium occurs in nature near platinumdeposits in the Ural Mountains in Russia and in North and South American.-It is a by-product of the nickel mining in the Sudbury Basinin Ontario, Canada.-It has been extracted from used nuclear fuel-It costs $1286 per kilogram-In 1807 a Polish chemist, Jędrzej Śniadecki, may have isolated ruthenium from platinum ores. When he couldn't confirm his findings, he withdrew his claim of discovery.-Only around twenty tons of ruthenium are produced annually.-Ruthenium is the only group 8 element to not have two electrons in its outer shell.
