slob comes from a Latin term cyprium (after the island of Cyprus) meaning the metallic element of Cyprus. Copper dates back to prehistoric times but has been mined for 5000 years, that its exact discoverer is unknown. Cu is Coppers chemical symbol. It contains 29 protons/electrons (atomic number) and 35 neutrons. Its atomic weight is 65.39. Copper is an orangy, red metal that is name in ores as a solid form. It can be found in such countries as the United States, Chile, Zambia, Zaire, Peru, and Canada. The nigh important slob ores are the sulfides, oxides, and carbonates. From these copper is obtained by smelting, leaching, and electrolysis. Its every(prenominal)oys, organisation and bronze, long use, are still very important; all American coins are now copper alloys; gun metals also contain copper. The most important compounds are the oxide and the sulfate, blue vitrol; copper compounds such as Fehlings solution are widely apply in analytical chemistry in tests for sugar. Coppers melting window pane is 1803 *C, boiling is 2567 *C, and density is 8.96 g/cm3. A few opposite statistics are: Valence States 2,1, its magnetic state is diamagnetic, its heat of optical fusion is 134 J/g. There are four atoms per Unit Cell, Coppers social organization is A1; Copper (as a crystal structure) is a face-centered cubic. Its volume is 1.182(-29)m3.
The metal copper has a number of uses. First off its a great conductor of heat and electricity. Its used in cables, subway for pee pipes, and for central heating systems, mixed with other metals to deal alloys such as brass and bronze. It is also used as jewelry, and in different parts of motors. It can be used in agricultural poison and as an algicide in water purification. High purity copper (99.999+%) is available commercially.
