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.
English: This chart shows the nominal price of gold along with the price in 1971 and 2011 dollars (adjusted based on the consumer price index). The historical gold price was obtained from www.igolder.com; CPI was obtained from www.rateinflation.com.
The material, known as Metglas, was commercialized in the early 1980s and became used for low-loss power distribution transformers (amorphous metal transformer). Metglas-2605 is composed of 80% iron and 20% boron, has a Curie temperature of 646 K (373 °C; 703 °F) and a room temperature saturation magnetization of 1.56 teslas. [7]
The gram-atom is a former term for a mole of atoms, and gram-molecule for a mole of molecules. [ 7 ] Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass ( M r ). [ 8 ]
Here the "unified atomic mass unit" refers to 1/12 of the mass of an atom of 12 C in its ground state. [13] The IUPAC definition [1] of relative atomic mass is: An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12 C.
In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc).

PT Perusahaan Rokok Tjap Gudang Garam Tbk (Republican spelling Indonesian for "Salt Warehouse brand Cigarette Company plc"), trading as PT Gudang Garam Tbk, is an Indonesian tobacco company, best known for its kretek (clove cigarette) products. It is Indonesia's largest tobacco manufacturer, with a market share of nearly 33%. [1]
The dalton (symbol: Da) is the standard unit that is used for indicating mass on an atomic or molecular scale (atomic mass). [1] The unified atomic mass unit (symbol: u) is equivalent to the dalton. One dalton is approximately the mass of one a single proton or neutron. [2] The unified atomic mass unit has a value of 1.660 538 921 (73) × 10 ...
