  2. Copper - Wikipedia

    en.wikipedia.org/wiki/Copper

    In volume, copper is the third most recycled metal after iron and aluminium. [47] As of 2023, recycled copper supplies about one-third of global demand. [48] The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps.

    Iron-carbon phase diagram. α-Iron is a fairly soft metal that can dissolve only a small concentration of carbon (no more than 0.021% by mass at 910 °C). [133] Austenite (γ-iron) is similarly soft and metallic but can dissolve considerably more carbon (as much as 2.04% by mass at 1146 °C).

    Like oxide, fluoride is a highly basic anion [19] and is known to stabilize metal ions in high oxidation states. Both copper(III) and even copper(IV) fluorides are known, K 3 CuF 6 and Cs 2 CuF 6, respectively. [1] Some copper proteins form oxo complexes, which also feature copper(III). [20]

    The characteristic properties of elemental metals and nonmetals are quite distinct, as shown in the table below. Metalloids, straddling the metal-nonmetal border , are mostly distinct from either, but in a few properties resemble one or the other, as shown in the shading of the metalloid column below and summarized in the small table at the top ...

  9. Copper(II) oxide - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_oxide

    Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite, or sometimes black copper.
