  2. Prices of chemical elements - Wikipedia

    en.wikipedia.org/wiki/Prices_of_chemical_elements

    This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.

  3. Osmium - Wikipedia

    en.wikipedia.org/wiki/Osmium

    Osmium (from Ancient Greek ὀσμή (osmḗ) 'smell') is a chemical element; it has symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element.

  4. Platinum group - Wikipedia

    en.wikipedia.org/wiki/Platinum_group

    Osmiridium is a naturally occurring alloy of iridium and osmium found in platinum-bearing river sands in the Ural Mountains and in North and South America. Trace amounts of osmium also exist in nickel-bearing ores found in the Sudbury, Ontario, region along with other platinum group metals. Even though the quantity of platinum metals found in ...

  5. Precious metal - Wikipedia

    en.wikipedia.org/wiki/Precious_metal

    Gold nugget A selection of precious metal elements; gold, silver, platinum, palladium, copper, ruthenium, rhodium, rhenium, osmium, iridium and mercury. They are labeled and arranged by their location on the periodic table. Precious metals are rare, naturally occurring metallic chemical elements of high economic value.

  6. Rhodium - Wikipedia

    en.wikipedia.org/wiki/Rhodium

    Solid (pure) rhodium jewelry is very rare, more because of the difficulty of fabrication (high melting point and poor malleability) than because of the high price. [48] The high cost ensures that rhodium is applied only as an electroplate. Rhodium has also been used for honors or to signify elite status, when more commonly used metals such as ...

  7. Spot contract - Wikipedia

    en.wikipedia.org/wiki/Spot_contract

    In finance, a spot contract, spot transaction, or simply spot, is a contract of buying or selling a commodity, security or currency for immediate settlement (payment and delivery) on the spot date, which is normally two business days after the trade date. The settlement price (or rate) is called spot price (or spot rate).

  8. Synthesis of precious metals - Wikipedia

    en.wikipedia.org/wiki/Synthesis_of_precious_metals

    Rhodium has the highest price of these precious metals ($440,000/kg in 2022 [3]), but the cost of the separation of the rhodium from the other metals needs to be considered [editorializing], although recent high prices may create opportunity for consideration.

  9. Ruthenium - Wikipedia

    en.wikipedia.org/wiki/Ruthenium

    Like iron but unlike osmium, ruthenium can form aqueous cations in its lower oxidation +2 and +3 states. [ 13 ] Ruthenium is the first in a downward trend in the melting and boiling points and atomization enthalpy in the 4d transition metals after the maximum seen at molybdenum , because the 4d subshell is more than half full and the electrons ...
