Osmium! Osmium! Osmium! We here at Platinum Family Industries are crazy about Osmium and with good reason! This rare element (Which has the chemical symbol of 'Os') has the atomic number of 76 and an atomic mass of 190.23u. It is a transition metal, belonging to the Platinum Family.

Known Types (Isotopes) Of Osminium: There are seven known isotopes of Osminium: 1) 184 Os 2) 187 Os 3) 188 Os 4) 189 Os 5) 190 Os 6) 192 Os (One of the most abundant) 7) 186 Os (One of the most abundant)

The University of Nottingham's professors discuss Osmium.

Product Information (Physical Properties): - Color: The color of Osmium is a blue-gray and/or blue-white tint. - Hardness: Osmium is very hard, ranking as one of the hardest elements on the table. It is also brittle, even in high temperatures, along with being a lustrous metal. - Density: Osmium is the densest metallic and stable element. It has a room temperature density of 22.57(g/cc). - Phase of Matter at Room Temperature: Solid. - Ductility and Malleability: Like most transition metals, Osmium is both ductile and malleable. - Melting Point: Osmium's melting point is 3033 degrees celsius. - Boiling Point: Osmiun's boiling point is 5012 degrees celsius.

Atomic Radius: 135pm

Electronegativity: 2.2

Did you know? Osmium comes from the Greek word 'Osme' meaning smell. Platinum also reached Europe as 'Platina' meaning small silver.

Chemical Information (Properties) - Oxidation states: Mildly acidic oxide with the states of; 8, 7, 6, 5, 4, 3, 2, 1, 0, -1 and -2. - This is a very highly reactive and toxic element.

The History of Osmium Osmium was discovered in 1803 by Smithson Tennant (Left) and Hyde Wollaston in London, England. The discovery of osmium is intertwined with the other metals of the platinum group. They always observed a small amount of a dark, insoluble residue. In 1803, Smithson Tennant studied the insoluble residue and decided that it must contain a new metal. Vauquelin treated the powder differently with alkali and acids and retrieved a volatile new oxide, which he believed to be of this new metal—Which he named Ptene. However, Tennant, who had a much larger quantity of residue, continued his research and identified two previously unknown elements in the residue, Iridium and Osmium.

The Use of Osmium Why use Osmium? This element is perfect for producing very hard alloys with other metals of the platinum group, for fountain pen tips, instrument pivots, electrical contacts, detecting fingerprints to stain fatty tissue for microscope slides and is used in implants such as pacemakers.
