Metallic chemical element symbol Rh name is derived from the Greek word meaning rhodon and Zuhri. And is a shining silvery color ovary. Aotair rhodium and one of the transition elements of the periodic table and the atomic number 45 and atomic weight 102.905 and melting point 1966 degrees Celsius and a boiling point of 3727 degrees Celsius and density of 12.4 g / cm 3. Rhodium was discovered in 1803 by the British and William Hyde Wollaston before chemotherapy. And rhodium component built into it is not very soluble in ordinary acids and very difficult goodwill and hardness according to Mohs scale is 4 degrees. Rhodium compounds show oxidation numbers ranging from 1 to 6. Mahalih and water for most of its salts with pink color and here is derived from his name. There rhodium in platinum ores in metal Aloozimiradiom and also found in gold -alrodiom in metal ores known as Alrudayt. And it occupies the first place and eighty in terms of the proportion of its presence in the earth's crust. Rhodium in alloying with platinum is used where these alloys intervention in industry thermocouples for measuring high temperatures. Rhodium is also used pure Kstah reflective mirror in the lights. The Black Rhodium is a metal powder and contains some oxides and Alheidredat is used as a catalyst and Kbbag black dye porcelain tools.
the cost per gram is about $ 300, this metal makes strange soft materials harsh. This property is exploited Weber gas industry hardener for their products. Radium is used widely in car exhaust industry, where radium in Ketelizatr able to convert harmful gases into harmless gases such as nitrogen and carbon dioxide.
* Supernova: is a type of supernovae and expression shows several massive stellar explosions which aims its cover star in space at the end of its life. Lead to the formation of spherical cloud around the star very glamorous (severe sparkles) of plasma.
* Mohs scale: Scale is used to denote the ability of different materials to resist scratching any amount Slaptha.oeetm by examining the ability of a solid material to scratch material hardness less of them.
