Basic Information
Platinum has an atomic number of 78 and an atomic mass of 195.08. It has 117 neutrons in its nucleus. platinum at room temperature is a solid metal. It has a melting point of 2041.4 K [or 1768.3 C (3214.9 F)] and a boiling point of 4098 K [or 3825 C (6917 F)]. Platinum was discovered very early by Ancient Indians but later by Antonia de Ulloa in 1735

The word platinum was derived from the spanish word platina which means "little silver". Platinum is a dense, malleable, ductile, precious, gray andwhite transition metal. It is one of 6 elements in the platinum group of elements. Platinum has six naturally occuring isotopes platinum is the least reactive metal and is one of the rarest elements in earths crust. Platinum is remarkably resistant to corrosion even at extremely high temperatures, therefore it is considered a noble metal. Platinum cost about 100 more dollars the gold does. It cost about 1432.60 dollars per ounce.

** History of Platinum **
Platinum has quite the confusing history. Platinum was used by pre-Columbian Indians but was rediscovered in South America by Antonio de Ulloa in 1735 and Wood in 1741. In 1822 plenty of platinum was discovered in the Ural Mountains of Russia. Increased platinum use was limited due to its supply. In 1820, Columbia, still the one of the only major producers of platinum in the world, stopped exporting the metal. Then in 1822, in Russia platinum was proved to be present in the gold fields of the mountains. Over the next 18 years, the Russian government mined almost 500,000 ounces of platinum and introduced to the world the fact that platinum was like gold, extremely valuable.

Platinum was fist used by blacksmiths to make jewlry and was also used for the making of glass. In the 18 century platinum was used to make durable laboratory equipment in Berlin. In the late 19 century platinum began to be used in the development of gun parts. It was also used in sophisticated batteries and fuel cells. media type="youtube" key="X09zSQSUXDk" width="560" height="315" There are many uses of platinum today. The best known use of platinum today is as the catalyst converter. A catalyst converter is part of the exhaust system in the automobile. Instead of emitting harmful carbon monoxide gases it converts them into harmless carbon dioxide and waters. platinum is also used in fertilizers and explosive gauze for the conversion of ammonia into nitric acid. Platinum is in coating missile tips. It is used to make jewelry. It is used in anti-cancer drugs and implants.
