Bronzes. A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%. Iron, nickel, manganese and silicon are sometimes added.
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.
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 ...
The discoveries of the 118 chemical elements known to exist as of 2024 are presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined. There are plans to synthesize more elements, and it ...

Copper (I) sulfide is a copper sulfide, a chemical compound of copper and sulfur. It has the chemical compound Cu 2 S. It is found in nature as the mineral chalcocite. It has a narrow range of stoichiometry ranging from Cu 1.997 S to Cu 2.000 S. [ 4] Samples are typically black.
Zinc. hexagonal close-packed (hcp) ( hP2) Zinc is a chemical element with the symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table.
Basic copper carbonate is a chemical compound, more properly called copper (II) carbonate hydroxide. It can be classified as a coordination polymer or a salt. It consists of copper (II) bonded to carbonate and hydroxide with formula Cu2(CO3) (OH)2. It is a green solid that occurs in nature as the mineral malachite.
