     Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society.
Copper has many chemical properties that make it unique. The Atomic number of copper is 29. An Atomic number is a measure of the amount of protons in the nucleus of an atom. Protons are sub-atomic particles, which have a positive charge. The Atomic mass of copper is 63.546. The Atomic mass is a measure of how many neutrons and protons are in an atom. Neutrons are sub- atomic particles, which have no charge. Thus, using the Atomic mass and Atomic number of Copper, we can determine that it has 29 proton and 35 neutrons.
Copper is a transition element and is found in column eleven of the periodic table. That means that it has 11 electrons in it valence shell. A valence shell of an atom is the last shell of electrons. Copper is a metal, which lies in period 4 of the Periodic table.
     Other basic properties include having a density of 8.96grams/ centimeters3. Density is a measure of mass per unit of volume in a substance. Copper has a melting point of 1083.3 degrees Celsius. A melting point of a substance is the temperature at which a solid changes to a liquid. Also, the freezing point of Copper is 2567 degrees Celsius. The freezing point of substance is the temperature a liquid changes to a solid.
     There are also many physical properties of Copper including conductivity, malleability, ductility, and the resistance against corrosion. Conductivity is the ability to conduct electricity. Silver is the only better conductor of electricity, but it is too expensive. Pure copper is a better conductor of electricity than copper alloys, due to the impurities in the alloys. Copper is also

very malleable. Malleability is the ability to be easily shaped. Copper doesn’t break when hammered, stamped, forged, or spun into unusual shapes. Copper can be shaped either in a hot or cold shape. Besides being easily shaped, Copper is dutiable. Ductility is the ability to be drawn into thin wires without breaking. When heated, Copper becomes very ...

throughout the world; fifty nations mine it today. Some include Albania, Argentina, Peru, Russia, Zambia, and many more. The largest miners of copper are Chile and the United States. Other major producers include Canada, Australia, and Indonesia. Within the United States, the leading states of production include, Arizona, Utah, Montana, and Nevada.
     Copper is essential to modern society. Its uses are numerous and essential to many animals. Since the discovery of Copper, it has been an integral part of industry, art, and agriculture. Today’s uses would not be possible if not for the discoveries many, many years ago.

So the pure copper, which was found, was what they had found otherwise it was obtained from copper bearing ores. In due time it was discovery that copper and tin could be combined to form bronze, this was through heating the metals. The metals were placed into a clay crucible and then heated at a very high temperature inside a kiln containing a charcoal fire. Following the implementation of copper extraction, it was discovered that the process of combing metals gave them superiorities like strength, in bronze....   [tags: 29th element, symbol, metals]
