Copper is a chemical element with symbol Cu and atomic number 29, known for its high thermal and electrical conductivity.
Alchemical symbols were used to denote chemical elements and compounds, ... or copper for Mars instead of iron; however, gold, silver, ...
Copper occurs in its native form in Chile, China, Mexico, Russia and the USA. Various natural ores of copper are: copper pyrites (CuFeS 2), cuprite or ruby copper (Cu 2 O), copper glance (Cu 2 S), malachite (Cu(OH) 2 CuCO 3), and azurite (Cu(OH) 2 2CuCO 3). Copper pyrite is the principal ore, and yields nearly 76% of the world production of copper.
Mineral symbols (text abbreviations) are used to abbreviate mineral groups, subgroups, and species, just as lettered symbols are used for the chemical elements. The first set of commonly used mineral symbols was published in 1983 and covered the common rock-forming minerals using 192 two- or three-lettered symbols. [ 1 ]
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion . Of the large number of different types, the best known traditional types are bronze , where tin is a significant addition, and brass , using zinc instead.
The Phoenix-based corporation produced 4.2 billion pounds of copper in 2024, along with gold and other metals. Freeport earned a profit of $6.9 billion last year on $25.5 billion in revenue.
The number of atoms of an element in a molecule or chemical compound is shown in the right subscript position (e.g., N 2 or Fe 2 O 3). If this number is one, it is normally omitted - the number one is implicitly understood if unspecified. A radical is indicated by a dot on the right side (e.g., Cl • for a neutral chlorine atom).
