Copper Essay -- essays research papers

Weil 1 bulls eye is one of the earliest elements cognise to man. Because of its distinct red color, bulls eye is very easily identified. In the superannuated times, copper could be put in lying in the ground in its unattached state without interaction to other tendernesss. copper color and its compounds have umteen uses in todays society. Copper has many chemical properties that fuck off it unique. The Atomic number of copper is 29. An Atomic number is a notice of the amount of protons in the nucleus of an atom. Protons are sub-atomic particles, which have a coercive charge. The Atomic mass of copper is 63.546. The Atomic mass is a circular 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 jibe 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 suppress. A valence shell of an atom is the last shell of electrons. Copper is a surface, which lies in period 4 of the Periodic table. other(a) basic properties include having a density of 8.96grams/ centimeters3. Density is a greenback 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. on that point are also many physical properties of Copper including conductivity, malleability, ductility, and the resistance against corrosion. conduction is the ability to conduct electricity. Silver is the only better conductor of electricity, merely 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 Weil 2very malleab le. Malleability is the ability to be easily shaped. Copper doesnt recession when hammered, stamped, forged, or spun into unusual shapes. Copper can be shaped each in a hot or cold shape. Besides creation easily shaped, Copper is dutiable. Ductility is the ability to be drawn into trim back wires without breaking. When heated, Copper becomes very ... ...s its red color from the iron. The other substance, hemocryanin is the same as hemoglobin, except it uses copper quite of iron. Thus it has a blue color, instead of red. Examples of animals, which have hemocryanin, are crustaceans. Copper is very numerous in nature. The metal ranks in the upper quarter of elements abundant in the earths crust. A lowly part can also be found in seawater. Copper is minded Weil 4throughout the world fifty nations mine it today. roughly include Albania, Argentina, Peru, Russia, Zambia, and many more. The largest miners of copper are Chile and the United States. otherwise 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 stripping of Copper, it has been an integral part of industry, art, and agriculture. Todays uses would not be affirmable if not for the discoveries many, many years ago.
