  2. 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. It is a product of copper mining and the precursor to many other copper ...

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

    Infobox references. Copper (I) oxide or cuprous oxide is the inorganic compound with the formula Cu 2 O. It is one of the principal oxides of copper, the other being copper (II) oxide or cupric oxide (CuO).The compound can appear either yellow or red, depending on the size of the particles. [2] Cuprous oxide is found as the mineral cuprite.

  4. Copper - Wikipedia

    Copper. face-centered cubic (fcc) (cF4) Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity ...

  5. Copper oxide - Wikipedia

    en.wikipedia.org/wiki/Copper_oxide

    Copper oxide is any of several binary compounds composed of the elements copper and oxygen. Two oxides are well known, Cu 2 O and CuO, corresponding to the minerals cuprite and tenorite, respectively. Paramelaconite (Cu 4 O 3) is less well characterized. [1] Copper oxide may refer to: Copper(I) oxide (cuprous oxide, Cu 2 O) Copper(II) oxide ...

    e. The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties. All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.

    Their superconducting properties are determined by electrons moving within weakly coupled copper-oxide (CuO 2) layers. Neighbouring layers contain ions such as lanthanum , barium , strontium , or other atoms which act to stabilize the structures and dope electrons or holes onto the copper-oxide layers.

  8. Delafossite - Wikipedia

    en.wikipedia.org/wiki/Delafossite

    Delafossite is a copper iron oxide mineral with formula CuFeO 2 or Cu 1+ Fe 3+ O 2. It is a member of the delafossite mineral group, which has the general formula ABO 2, a group characterized by sheets of linearly coordinated A cations stacked between edge-shared octahedral layers (BO 6). [5] Delafossite, along with other minerals of the ABO 2 ...

  9. Copper(II) carbonate - Wikipedia

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

    Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO 3. At ambient temperatures, it is an ionic solid (a salt) consisting of copper(II) cations Cu 2+ and carbonate anions CO 2− 3. This compound is rarely encountered because it is difficult to prepare [2] and readily reacts with water moisture from the air.
