Osmium is a chemical element with symbol Os and atomic number 76. Classified as a transition metal, Osmium is a solid at room temperature.
Is osmium a metal or nonmetal?
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.
What is osmium classified?
Data Zone Classification: Osmium is a transition metal Color: bluish-white Atomic weight: 190.2 State: solid Melting point: 3030 o C, 3303 K.
What family does osmium belong to?
Osmium is an element in Group 8 (VIIIB) of the periodic table. The periodic table is a chart showing how chemical elements are related to one another. Osmium is also a member of the platinum family. This family consists of five other elements: ruthenium, rhodium, palladium, indium, and platinum.
Is osmium a rare metal?
Osmium is rare and has some distinctive properties that make it a fascinating element. It is plopped in the middle of the periodic table and has some mighty strange neighbors, some of which don’t really exist (1). But it also has some valuable neighbors – palladium, silver, platinum, and gold (Figure 1).
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.
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 symbol of osmium?
Os
Where is osmium most commonly found?
Sources of osmium The element occurs in the mineral iridosule and in platinum-bearing river sands in the Urals, North America and South America. While there is little osmium in these products, it can be easily obtained from processed nickel ores.
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.
What is the heaviest metal in the world?
Osmium is one of the heaviest materials on earth, weighing twice as much as lead per teaspoon. Osmium is a chemical element in the platinum group metals; it’s often used as alloys in electrical contacts and fountain pen nibs.
Which metal has the least density?
Under standard conditions, lithium is the lightest metal and the least dense solid element. It is a soft, silver-white metal belonging to the alkali metal group of chemical elements.
Which metal has highest density?
The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.
Is osmium toxic to humans?
Health effects of osmium Osmium tetroxide, OsO4, is highly toxic. Concentrations in air as low as 10–7 g m–3 can cause lung congestion, skin damage, and severe eye damage.
What is the most expensive metal?
Rhodium: Top Most Valuable Metal Rhodium is the most valuable metal and exists within the platinum group of metals. It is used in jewelry for a final finish on white gold jewelry.
What is the rarest metal on earth?
The rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.
Can you crush a diamond with a hammer?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure. Diamonds, because of their lack of flexibility in the structure, are not actually very strong at all.
What is the strongest thing on earth?
The World’s Strongest Stuff Diamond. Unmatched in its ability to resist being scratched, this much-loved gemstone ranks the highest in terms of hardness. Graphene. Spider silk. Carbon/carbon composite. Silicon carbide. Nickel-based super-alloys.
What is the hardest thing in the universe?
Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
Is osmium more expensive 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.
Which is the lightest metal in the world?
Magnesium is the lightest structural metal and abundantly available in the earth’s crust and seawater. Magnesium is the third most commonly used structural metal, following steel and aluminum.
Is osmium the strongest metal?
Osmium is the densest substance known and the hardest of all platinum group metals (PGMs). It is ten times harder than platinum itself. Osmium also has a higher melting point than the other platinum group metals.
What is the difference between osmium 192 and osmium 190?
Osmium isotopes are used for the production of radioisotopes and in scientific experiments. Os-192 can be used for the production of the medical radioisotope Pt-195m. Os-190 has been used as a tracer to determine Os abundance in meteorites using isotope dilution ICP-MS.
What is osmium found in?
1803.
How do I get osmium?
Osmium is a Metal Commodity. It cannot be purchased from Commodities Markets, and must be mined from asteroids in metallic or metal-rich Planetary Ring Systems.
Is osmium stronger than tungsten?
After only a few years, osmium was replaced by the more stable metal tungsten. Tungsten has the highest melting point among all metals, and its use in light bulbs increases the luminous efficacy and life of incandescent lamps. The only known clinical use of osmium is synovectomy in arthritic patients in Scandinavia.
What does osmium smell like?
Osmium tetroxide has a characteristic, unpleasant, irritating odour similar to that of chlorine and ozone with a touch of garlic.
Is osmium used in jewelry?
In jewelry designs, it is sometimes used in a dark color known as black ruthenium. Osmium – While it’s the densest element, osmium can be brittle in jewelry so its design should be considered carefully. Pure osmium can also be toxic in its natural form, where it has a bluish-white color.
