Created with Fabric.js 1.4.5 Devon.T.Stephens Bell:2 Ruthenium Ruthenium has 44 Electrons Ruthenium has 57 Nuetrons Ruthenium has 44 protons Chemical Properties of Ruthenium Small amounts of ruthenium improve the corrosion resistance of Titanium. Ruthenium is relatively non-reactive It does not dissolve in most acids including Aqua regia, a mixture of hydrolic and nitric acids. Physical Properties of Ruthenium Ruthenium's boiling point is about 3,900c to 4,150c I'ts density is 12.41 grams per cubic centimeter Ruthenium is a hard silvery white metal with a shiny surface Ruthenium has 5 Energy Rings History Sniadecki discovered the element 44 in 1808 while working with platinum ores in South Africa.Other chemist tried to find Ruthenium but failed,Sniadecki was discouraged and dropped his claim.20 yrs later the Ruthenium was discovered again by Russian chemist Gottfried.W.Osann. Once again chemist could not repeat Osanns results. There was another argument over wether Ruthenium was realy found. Finally in 1844 Russian chemist CarlEarnst Claus gave positive proof of a new element found in Platinum ores.Claus suggested calling the element Ruthenium, after the ancient name ofRussia,Ruthenia.Osann had suggested that name as well. Used in the manufacturing of alloys. Used for chip resistors and electrical contacts. Uses Used to coat Anodes of electrochemical cells for chlorine production. Used in catalysts for ammonia and acetic acid production. Used in solar cells,which turn light energy into electrical energy. It is unafected by water,air,and acids but can be desolved by molten Alkalis. Does not tarnish at room temperatures,but oxides in air at about 800c Ruthenium together with rhodium,palladium,osmium,iridium,and platinumform a group of elements referred to as the the platinum group metals (PMG).
