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 ...

...s its red color from the iron. The other substance, hemocryanin is the same as hemoglobin, except it uses copper instead 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 small part can also be found in seawater. Copper is minded
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.

- Purpose The purpose of this experiment is to use our knowledge from previous experiments to separate a copper compound and from there make calculations relevant to the experiment. The calculations that we had to make in this experiment had to do with finding the percentage of copper in copper compound and from there find the formula weight of the copper compound. Question or Problem The question that was proposed by the instructor for investigation was: Can the % composition of an element in a compound be determined accurately (Lab Manual 61)....

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]

- Electrolysis of Copper in Copper Sulphate Solution Introduction Aim This is an investigation into how temperature affects the amount of copper lost from the Anode and gained on the Cathode during electrolysis. Electrolysis isâ€¦ The chemical change by passing electric charge through certain conducting liquids (electrolytes). The current is conducted by migration of ions - negative ones from the Anode (positive electrode), and positive ones to the Cathode (negative electrode).... [tags: Papers]

I look down into the creek as I sit here munching on some cashews, and I see trout gliding effortlessly through the crystal-clear water. I revel in how incredibly lush the area is…although it’s been a dry summer the ground is still moist, plants are bright and colorful, and wildlife is abound. After I finish my snack and tuck my trash away into my backpack, I continue my hike up this parcel of land that is may soon become barren with towers of steel and wire draping the landscape....

- Copper Mining Copper mining has become a very important industry in today’s society. It is also one of man’s oldest commercial activities. There are many steps from finding a mine site to producing a product made of copper or a copper alloy. The mining industry has also had many important developments from the time the first mine was formed in Rio Tinto in 3000 B.C. The earliest copper sources were globules and chunks of native copper found on the Earth’s surface. After we quickly exhausted the limited amount of native copper, we were forced to look underground for more sources.... [tags: Natural Resources Minerals Miners Essays]
