Research Paper On Copper

The discovery of copper does not have an exact date. Copper is said to be a prehistoric element. This element was said to be first discovered around 8000BC. The ancient civilizations started to take the copper out of the ore they found around 4000BC. This is when copper started to be put to good use. Early civilizations discovered that copper is malleable and is sharp. They realized they could make copper into tools and weapons. This was easier than the stone that they were originally using. This helped a lot because stones were harder to carve, but copper is easy to bend and shape. But what exactly is the element copper? Copper found in the periodic table in Group eleven. Copper is located right before the element gold and the element sliver.
Copper is ductile, malleable, and a good conductor of heat and electricity. Since copper is a very good conductor of electricity, a lot of electrical wires are made out of copper. This helps easily transfer electricity. Electrons move candidly in copper because they are ready to bond with another atom to form an stable octet. An octet is eight valence electrons in the outer energy level. Having eight in the outer energy level will make the ion stable. Copper has a germicidal effect meaning that many germs are neutralized by it. This is why it is often used in things like doorknobs because of its automatic disinfecting qualities. This is also why copper was used in ancient days to treat wounds. (Hamilton, 2003-2008). Copper is also found in a lot household items. For example lightning rods, washer, dryer, televisions, cell phones, pipes, and even refrigerators. The only bad thing about having copper pipes in a house is that if that house gets struck with lightning the pipes could cause damage to the house. The element Copper was actually used to make the Statue of Liberty. Now all that is seen is a big green lady but really the copper reacted with the oxygen in the air. That process is called oxidation and that is why lady liberty is green. Fun fact, the amount of copper used on the Statue of Liberty could make 30 million pennies. (NCFL, 2014-2016). Copper is also very efficient and good for this earth. This is because
This is formed because copper looses the one valence electron and forms a cation. A cation is formed when an atom looses its valance electrons and as a result the atom is positive. If the ion was gaining two electrons then the ion would be negative. A negative ion is called an anion.
Copper has a boiling point of 3200 Kelvin. This is a very average boiling point for many transitions metals. The melting point for copper is 1357.77 Kelvin. This is also a very normal melting point for many transition metals.
The density of copper is 8.96 g/cm3. This is when copper is at room temperature and still a solid. When copper is at melting point the density is 8.02 g/cm3 . This is when copper is now in a liquid form.
In the periodic table copper can be found in period 4 group 11. This is where the coinage metals are found. Copper is found in the middle of the periodic table. The middle area of the periodic table is where the transition metals are located. Copper is one of the most important transition metals for human life. Copper is used in our everyday life from house items, conducting electricity, and money. Copper is taken for granted even if it is used every single
