Copper is a chemical element with atomic number 29 and symbol Cu. The density of copper is 8.96. The atomic number of copper is 29.
For thousands of years, copper has been a metal that has been part of our civilization. Silver, gold, copper and iron were used in one form or another.
Copper (Cu) is one of those elements that was never really discovered. They were part of every step in the growth of civilization. We continue to visit the different places where copper is used in nature.
The metal has been used for so long that it can be found isolated as an unadulterated element. Someone could be tunneling in a mine and stumble across unadulterated copper in various forms.
It is the 29th element in the periodic table represented by the symbol 'Cu', short for the Latin name 'cuprum'.
Copper is soft but tough. It is easily mixed with other metals to form alloys such as bronze and bronze. Bronze is an alloy of tin and copper, and brass is an alloy of zinc and copper. Copper and brass are quickly recycled. Perhaps 70% of the copper currently in use has been recycled at least once.
Copper sulfate is widely used as an agricultural poison and as an algaecide in water purification.
While copper cannot be considered to be used for anything other than coins, it is a crucial element in the creation of bronze.
Historically, copper was the first metal to be worked by man. The discovery that it could be hardened with a little tin to form the bronze alloy gave its name to the Bronze Age.
It is used for a wide range of products, from cans, aluminum foil and pans to electrical cables, airplanes and space vehicles.
Electrical conductivity is especially important because wire accounts for more than 50% of copper consumption worldwide.
Chemical vapor deposition, which is used in semiconductor manufacturing, involves the deposition of thin copper films from a precursor in the gas phase.
Copper is primarily used as an alloy of gold and silver, and is often plated with one or the other.
