Copper
Copper is a mineral. it is not a plant or a animal. Copper
is a metallic metal. It can never be broken down into differnet substances by
normal chemical means. Copper was one of the first metals known to humans.
People liked it because in it’s native condition, it could easily be beaten
into weapons or tools. Copper has been one of the most useful metals for over
5000 years. Copper was probably used around 8000 B.C by people living along the
Tigris and Euphrates rivers. In 6000 B.C, Egyptians learned how to hammer copper
into things they wanted. Around 3500 B.C, People first learned how to melt
copper with tin to make bronze. So the period between 3000 B.C and 1100 B.C
became known as the bronze age.
Today, some of the leading states of the copper industry
are Arizona with 747,000 short tons, Utah with 187,000 short tons, New Mexico
with 161,000 short tons. Some other leading countries are Chile with 1,422,000
short tons, United States with 1,203,000 short tons, Soviet Union with 650,000
short tons, and Zambia with 596,000 short tons.

- Metal Essayexplanatory essayMetals are currently in high demand by society. A high percentage of common everyday items you use and see utilises a form of metal. That wooden table in a common kitchen that looks like it is made completely of wood. Metals are still used in that "completely wooden table" as the screws used to hold it together are made of metals. Many commonly used metals such as iron, aluminium, and/or copper are all found from ores. An ore is a mixture in the form of a rock that is mined. For example, bauxite is an ore that contains a high percentage of pure aluminium. That pure aluminium is then extracted, refined, and crafted in to many everyday items such as cars, foil, and ladders. Chemists are continuously researching an innovative approach to extract and refine pure metals from ores while using fewer amounts of energy. Society's requirement of metals is increasing by the year as science and technology advances.

It has a percent solubility of 100% in water, this meaning it dissolves at a very high rate. It is an electrolyte, also meaning that it has a sharp and stinging odor. This means it has a high rate of volatility and reflects low frequency wavelengths. Nickel cadmium is a good conductor, meaning it has a low viscosity level. It also has a lack of combustibility, and a high tendency of toxicity if ingested. One negative aspect of this compound is that once the body is exposed to it, there are many diseases, infections, and other things that can go wrong with the body. A positive aspect about it is that it is able to be used time repeatedly. Nickel cadmium is most likely not hazardous alone because whenever studies have been conducted to prove it, there have been other elements, like lead and cobalt, in the same experiment that could also be responsible for the results.
