Copper was discovered in 9000 BC in the Middle East. A pendant made of copper was found from 8700 BC. Since copper has been used since ancient times and is the oldest metal used by humans there is so definite scientist who discovered it. Copper is a ductile metal and a chemical element. It has an atomic mass of 63.546 AMU's, 29 protons and electrons, and 35 neutrons.…
In 1792 the currency of the United States penny was developed. The circle shaped structure was twice the size of the current penny as we know today. The penny was the United States first currency and Benjamin Franklin is to thank for that. The penny represents the foundation of our country and shows how much we have grown as a nation. But there has been a lot of controversy on whether or not the penny should be kept due to the fact it cost more to make the penny than it is to use it as currency.…
Percent Copper In Brass Lab Conclusion Emily Oleisky The purpose of this lab was to observe the amount of light a solution absorbs, and use the relationships in the Beer-Lambert Law to determine the quantity of a certain compound within a complex sample. First, the relationships between wavelength, concentration, and absorbance were determined. This lab focused on identifying the absorption of copper in various brass samples, and finding the percent copper in brass. In the first activity of the lab, the scientist was trying to determine the difference in molar absorptivity across various wavelengths of multiple salt solutions.…
The discovery of different types of metals such as copper helped in making stronger tools that were able to last for a longer period of time. During the latter part of the Stone Age, people found that by adding certain metals to copper it would create an even sturdier metal known as bronze. “They discovered that if you add just a little of another very rare metal, it makes the copper stronger. That metal is tin... ”(Gombrich, 9).…
Copper ore in Bingham Canyon, which is located 30 miles south of Salt Lake City, Utah was first discovered in 1848 . Later, it shaped to a more developed mining in 1906 and produced higher than 19 million tons which is the largest in any mine history. Originally, it was a mountain 108 years ago and sandstone, quartzite and limestones were the oldest sedimentary rocks here . During construction of the mine, the owner cleaned up all the historic workings and ground water.…
Chalcopyrite is a copper iron sulfide mineral. Its coloring is metallic brassy to a brown-orange, and on the Mohs scale, it has a hardness of 3.5 to 4. The chemical formula of chalcopyrite is CuFeS2. It is the most commonly occurring copper containing mineral in New Zealand, but it is only created near volcanic areas. On the metaphysical level, chalcopyrite is used for meditation, specifically for opening the third eye chakra (crown chakra), and physical healing.…

With special diets, vitamins, supplements, medication, and love and care, pets with this disease can still have a life with their family and loved ones.…
Copper is useful for many things; it is used to make metal wires, US coins, machinery, and gun metals. It is also used in water purification. Not only is it useful for everyday activities it is also used in your body. Everyday an adult Human needs 1.2 milligrams to help energy…
Artifacts of iron were found in Egypt dating from about 5000BC. There is evidence that iron was first being smelted around 5000 BC in Mesopotamia (IRAQ). Artifacts made of the smelted iron date back to 3000 BC from Egypt and Mesopotamia. Iron is the fourth most abundant element on Earth. It is a shiny gray metal.…
Tungsten is considered a strategic mineral because it is used in many ways. Tungsten has a high heat resistance; therefore, it has applications in things such as filaments in light bulbs, heating elements of heaters and furnaces, and if combined to make an alloy, it can be used in aircraft engines. It also is used often in artistic ways, like in pottery, particularly for a yellow tint, and can be substituted for gold and platinum in jewelry, wedding bands for example, because it is hypoallergenic and has a hardness of 7.5-8, so it is scratch-resistant. It also has a very high density, comparable to gold, as well as the highest melting point of any pure metal. Tungsten is mainly found in the wolfram group which includes ferberite, wolframite…
One of the earliest metals to be discovered, lead has a long history with mankind. It was first discovered around 7000 BC as a byproduct of silver smelting. Lead is metal known for its resistance against corrosion, malleability, and low melting point. Mined all across the world, lead was one of the most important metals in ancient times. Although lead was toxic, it was used widely, particularly in the Roman Empire.…
Iron smelting and forging technologies have existed in African societies between about 1000 and 500 B.C.E. The Iron Age is an important period in Africa that is often met with diffusion theories, on whether or not iron began there. Iron smelting, and other smelting is still used today in certain parts of Africa. Hitherto stone had been the strongest material around for making tools and weapons. Metal was a far more high quality raw material, compared to others, as it could be made into an infinitely wide range of shapes and sizes, for decoration and for trading, not just tools and weapons.…
