Ruthenium is a chemical element with symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. The Baltic German scientist Karl Ernst Claus discovered the element in 1844, and named it after Ruthenia, the Latin word for Rus' . Ruthenium usually occurs as a minor component of platinum ores; annual production is about 20 tonnes. Most ruthenium produced is used for wear-resistant electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys, and as a catalyst. Platinum belongs to the family of metals like ruthenium, rhodium, palladium, osmium, and iridium. Platinum dates back its origin to the Egyptian tombs in 1200 BC. The Egyptians during this time imported the metal platinum from Nubia.  It is one of the most expensive metals in the world which is very dense, soft, shiny, malleable, and ductile. Chemically, gold is a reactive solid chemical transition metal, included to a group 11 element. Platinum. The Platimum is a chemical element whose chemical symbol and atomic number are Pt and no. 78. The most expensive metals in the world. Not only the price is high, the quality of the metals itself is certainly unbelievable. So, if we want to sell it back, the price won’t go down. There are many people who invest on these most expensive metals in order to get a higher price in the next sale. Precious Metals The precious metals include: ruthenium, rhodium, palladium, silver, osmium, iridium, gold, and platinum. Their precious nature derives from the fact they are very scarce and unique among commodities in the manner in which they are judged as a measure of wealth. Iridium sells for about 40% of the value of rhodium (making it about four time more expensive than gold). Unlike most of the other precious metals, osmium oxidizes quite easily in air, and can give off poisonous fumes. Osmium is extremely hard and heavy, and has been useful in some applications. Cost, bulk: $650 per 100g. Source: Ruthenium is found free in nature often with the other platinum group metals. Commercially, it is obtained from pentlandite (a sulfide of iron and nickel) which contains small quantities of ruthenium. Small amounts of ruthenium are used to harden platinum and palladium and it can also be alloyed with these metals to make electrical contacts for severe wear resistance. The addition of 0.1% ruthenium improves the corrosion resistance of titanium a hundred times over. It is one of the most expensive metals in the world which has various colors, including a hard-brittle blue-gray and blue-black. The density of osmium is 22.59 g/ cm cubic, the second densest element. Ruthenium. The Ruthenium is a chemical element whose symbol and atomic number are Ru and no. 44. It is one of the most expensive metals in the world, the inert rare to most chemicals. It belongs to the platinum group of the periodic table whose name was given to it by Karl Ernst. The most expensive metals in the world. Not only the price is high, the quality of the metals itself is certainly unbelievable. So, if we want to sell it back, the price won’t go down. There are many people who invest on these most expensive metals in order to get a higher price in the next sale. Rhodium is a chemical element with symbol Rh and atomic number 45. It is a rare, silvery-white, hard, and chemically inert transition metal. It is a member of the platinum group. It has only one naturally occurring isotope, 103 Rh. Naturally occurring rhodium is usually found as the free metal, alloyed with similar metals, and rarely as a chemical compound in minerals such as bowieite and rhodplumsite. Rhodium is a silvery-white transition metal. It holds the distinction of being the world's most expensive precious metal. It has an atomic number of 45 and is about as nonreactive as gold. The only way to dissolve rhodium is with sulfuric acid. The World Rhodium Market. Rhodium — along with platinum, palladium, ruthenium, iridium, and osmium — is part of a group of elements referred to as the platinum group metals (PGMs) or platinum group elements (PGEs). Platinum group metals have similar physical and chemical properties, but rhodium is the rarest. 150 times more expensive than silver. In fact it's the most expensive of all precious metals. Yet no matter its rarity or cost, this metal is absolutely vital to the rapidly recovering automobile industry. The metal I'm talking about is rhodium.
