Osmium density

Osmium is the densest naturally occurring element, with a density of 22.59 g/cm3. But its density pales by comparison to the densities of exotic astronomical objects such as white dwarf stars and neutron stars Osmium is a densest metal found on the periodic table. The density of the metal is roughly 22,600 kg/m^ 3 which is attained by dividing mass over volume. It was discovered in 1803 by the English chemist, Smithson Tennant who used the Greek term, osme, or smell to describe its unpleasant odor Earlier, there was some confusion as to which one of the aforementioned metals is the densest metal known. However, after further research based on lattice parameters, the density of osmium was found to be slightly higher than that of iridium. Hence, at 20°C, it is the densest element

Osmium - Density - Os - Periodic Tabl

  1. Osmium har den högsta naturliga densiteten av alla grundämnen. Osmium är en spröd, extremt hård, blågrå metall. Bland annat på grund av sin stora hårdhet används metallen inom tekniken till exempelvis reservoarpennor och nålar för tonhuvud samt som katalysatorer och lageraxlar. Osmium har fått sitt namn från grekiskans osmí som betyder lukt
  2. Osmium is also the densest of all metals. Its density of 22.6 g/mL makes it 22.6 times heavier than water. Metal densities are all over the place, with the lightest metals being at the top of the periodic table and the heaviest at the bottom. Here are a few examples (in grams/mL)
  3. Density vs Specific Weight vs Specific Gravity I would like to point out that there are conceptual differences between density, specific weight and specific gravity. Follow the link if you want to learn more about these differences. With that said, this page will provide you the osmium density in kg/m³ (SI unit), g/cm³, g/ml, kg/l, lb/ft³
  4. However this proves not to be the case with the density of osmium at 0 K being 22,661 ± 11 kg m -3 compared to a value of 22,652 ± 11 kg m -3 for iridium. The difference of 9 ± 16 kg m -3 indicates an ambiguity and the possibility that iridium could be the densest metal statistically
  5. For osmium, which has a closer-packed hexagonal structure, the density is calculated from: where a and c = lattice parameters parallel to the a- and c-axes, respectively

Osmium has the lowast vapor pressure and the highest melting point among the platinum group of metals Osmium's density is slightly more than iridium hence is credited as the heaviest element Osmium can be dissolved by acids or aqua regia only if exposed to these liquids for a long period Osmium is slightly more dense than iridium, so osmium is often credited as being the heaviest element (calculated density ~ 22.61). The calculated density for iridium, based on its space lattice, is 22.65, though the element hasn't been measured as heavier than osmium

Osmium - Properties and Application

The density of metals ranges from Osmium at the highest density to lithium at the lowest density of any metal.. Knowing the periodic table is key for most scientists. But just merely knowing the name of each and every one of the elements is not enough Densitet, volymmassa är (enligt ISO 31) ett mått av ett ämnes täthet, således massa per volymenhet. [1] Ju högre densitet ett ämne har desto större är mängden massa per volymenhet; densiteten påverkar således direkt ämnets vikt.Ibland används specifik vikt som en synonym till densitet, men i vetenskapliga sammanhang kan begreppen vara väsentligt olika 1 - Osmium (Density Per Cubic cm: 22.59g) It doesn't get any heavier (per cubed cm) than Osmium. Weirdly its name comes from the Greek term osme, which means smell Osmium - Os General Information Discovery Osmium was discovered by S. Tennant in 1803 in London. Appearance Osmium is lustrous, bluish-white, extremely hard and has a pungent smell. Source Osmium occurs in the free state and in the mineral osmiridium, but commercial recovery is from the wastes of nickel refining. Use Osmium tetroxide is one of the most powerful oxidants for alkenes. The covalent attachment of osmium oxide to the double bonds of CNTs lattices was theoretically reported. Moreover, covalent linkage of [ruthenium-(4,4′-dicarboxy-2,2′-bipyridine)(2,2′-bipyridyl) 2](PF 6) 2 to ammonia-treated CNTs were studied
