Osmium | Definition, Properties, Uses, & Facts | Britannica
osmium (Os), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table and the densest naturally occurring element. A gray-white metal, osmium is very hard, brittle, and difficult to work, even at high temperatures.Of the platinum metals, it has the highest melting point, so fusing and casting are difficult.
