The name ruthenium comes from the Latin name for Russia, ruthenia, as this is where it was first discovered. Ruthenium was the final one of the six members of the platinum group to be discovered.Continue Reading
Russian chemist Gottfried Osann thought he discovered three new platinum metals in 1828, which he named polinium, pluranium and ruthenium. However, in 1944, another Russian chemist named Karl Klaus proved that Osann had only discovered a very impure form of ruthenium. As he was the first to isolate the element in its pure form, he is generally given credit for the discovery. However, he still chose to use the name thought up by Osann due to the fact that the original platinum ores the ruthenium was derived from were mined in Russia.
Ruthenium is only found with other platinum metals in a few places in the world, including the Ural Mountains in Russia. Specimens are also found in nickel mining operations in Ontario, Canada and in South African pyroxinite deposits.
Ruthenium is a very hard, silvery-white colored metal that quickly and sometimes violently oxidizes when exposed to air. Although it is extremely brittle, this metal is often used as a hardener that is added to other platinum metals. It is also sometimes added to titanium to make it more corrosion resistant.Learn more about Atoms & Molecules
In a chemical reaction, the reaction rate is faster when there is a higher concentration of reactants because there are more molecules present that can collide with one another. Collision theory explains this phenomenon, which is especially true for chemical systems that contain either gases or liquids as reactants.Full Answer >
Cesium is the softest metal on Earth. In fact, the metal is so soft, it is possible to cut it with a butter knife. Additionally, cesium melts at a relatively low temperature of 28.4 degrees Celsius (83.12 degrees Fahrenheit). Gold, silver and copper are other malleable metals considered "soft," but they are much harder than cesium.Full Answer >
The overall or net charge of any ionic compound must equal zero. Although ions themselves are either positive (cation) or negative (anion) by definition, the only way they can bond together and form a compound is by seeking an opposite charge.Full Answer >
C2H6 is the chemical formula for the compound ethane; it consists of a two carbon atoms connected by a single bond, with three hydrogen atoms bonded to each carbon for a total of six. Ethane has one of the most simple chemical structures of any organic molecules.Full Answer >
