The chemical element copper has the atomic number 29 and the symbol Cu. It has a high thermal and electrical conductivity and is a soft, malleable, and ductile metal. Pure copper has a pinkish-orange color when newly exposed.
Copper is a building material, a heat and electricity conductor, and a component of a number of metal alloys, including sterling silver, cupronickel, which is used to make marine hardware and coins, constantan, which is used to measure temperature in strain gauges and thermocouples.
One of the few metals (native metals) that can be found in nature in a form that can be used directly is copper. Because of this, humans began using the area around 8000 BC. Around 5000 BC, it was the first metal to be smelted from sulfide ores, thousands of years later; around 4000 BC, the first metal to be shaped in a mold; and bronze, the first metal to be intentionally alloyed with another metal, tin, around 3500 BC.
Copper(II) salts, which have long been used as pigments and frequently impart blue or green colors to minerals like azurite, malachite, and turquoise, are common compounds.
Copper roofing material oxidizes to a green verdigris (or patina) when exposed to air. Copper can be used as a pigment in compounds or as a pure metal in decorative artwork. Copper compounds are utilized as fungicides, wood preservatives, and bacteriostatic agents.
Because it is an essential component of the respiratory enzyme complex cytochrome c oxidase, copper is a trace mineral that must be consumed by all living things.
Copper is a component of the blood pigment hemocyanin in crustaceans and mollusks; in fish and other vertebrates, iron-complexed hemoglobin takes its place. Copper is mostly found in the liver, muscle, and bones of humans. Copper levels range from 1.4 to 2.1 mg per kilogram of body weight in adults.
