Two uses for Osmium:
>> With Iridium, an alloy used in making precision ball bearings & ball point pen points.
>> As a catalyst in the synthesis of Ammonia (NH3) and in the hydrogenation or organic compounds.
The letter O was already used as the symbol for oxygen. Therefore the symbol for Osmium was the first two letters of the element's name.
Osmium is a metal with a blue-gray appearance.
From Greek osmē, smell (from the strong odor of osmium tetroxide).Named osmium after http://www.answers.com/topic/greek-language osme meaning "a smell", because of the smell of the volatile osmium tetroxide
Smithson Tennant (in 1803) discovered and first isolated osmium.
The oxidation number of osmium in OsO3F2 is +6. In osmium trioxide (OsO3), each oxygen atom has an oxidation number of -2, so the sum of oxidation numbers of all atoms in the compound must equal the charge of the compound which is zero. Since there are two fluorine atoms each with an oxidation number of -1 in OsO3F2, the oxidation number of osmium must be +6 to balance the charges.
The most common isotope of osmium is 192 Os. All osmium isotopes contain 76 electrons.
There are two points in answer to your question: 1. Osmium is extremely expensive (it is a precious metal), and 2. Osmium is not manufactured, it is mined.
