What is osmium on the periodic table?
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.
How much osmium is in the world?
Osmium is the rarest of the stable elements: its average abundance in the Earth’s crust is about 1 gram per 200 tonnes.
Is osmium harder than diamond?
Researchers from us-based Lawrence Livermore National Laboratory (llnl) have discovered that osmium, a metal, is harder than diamond. It withstands compression better than any other material. Osmium powder and argon were placed in the hole and subjected to very high pressure of 600,000 atmospheres.
What is osmium used for today?
Osmium has only a few uses. It is used to produce very hard alloys for fountain pen tips, instrument pivots, needles and electrical contacts. It is also used in the chemical industry as a catalyst.
Is osmium rarer than gold?
Funnily enough, Os is considered as a platinum group metal. Additionally it is much rarer than gold, about 1000 times. Osmium is still not as expensive as Gold, being around $400 USD per ounce compared $1,300 USD per ounce.
Why is osmium so cheap?
Osmium is still not as expensive as Gold, being around $400 USD per ounce compared $1,300 USD per ounce. This is partly because it has very few commercial applications.
What are 5 uses of osmium?
Osmium has only a few uses. It is used to produce very hard alloys for fountain pen tips, instrument pivots, needles and electrical contacts. It is also used in the chemical industry as a catalyst. Osmium has no known biological role.
Why is osmium so expensive?
Osmium tetroxide is expensive because osmium is a rare element. Osmium is one of the rarest elements in the Earth’s crust. Osmium is obtained as a by-product from nickel and copper processing. The US production of Os is probably only about 75 kg/year.
What is the element osmium on the periodic table?

What are the physical characteristics of osmium silver?
Physical Characteristics. Osmium is a silver metal with a grayish blue tint. It is very hard and brittle. Osmium belongs to the platinum family. It is considered as the densest metal and have a density of around 22.59 g/cm 3 [4]. Osmium retains its lustrous shine even at high temperature and is very resistant to corrosion.
What happens when osmium is mixed with ammonia?
Osmium reacts with base, such as ammonia and forms nitride-osmates. Osmium reacts with halogens, and reacts with fluorine to form osmium pentafluoride, while forms tribromide, triiodide, and diiodide with other halogens.
How does osmium retain its lustrous shine at high temperature?
Osmium retains its lustrous shine even at high temperature and is very resistant to corrosion. Osmium has one of the highest melting and boiling points. It has the lowest vapor pressure among the members of platinum group.
