Origin : The name is derived from the Greek ‘osme’, meaning smell - the metal surface gives off a volatile osmium tetroxide, which has a characteristic odour.

Description :

A shiny silver metal that resists corrosion, and is the densest of all the elements and twice as heavy as lead. It is as rare as gold and, like gold, can be found as the free metal. It is little used except in a few alloys and in industry as a catalyst.
