Copper is a an element with atomic number 2n and atomic weight of 63.546.
It is one of the earliest metals to be used by humans. It has been in use by humans for over 10000 years. It was probably first used in 8000 B.C. by people living along the Tigris and Euphrates rivers in the Middle East.
It is reddish orange in colour. It is a very good conductor of electricity. For this reasons it is used widely for manufacturing electric power cables and other components using electricity.
It is also a very good conductor of heat. This makes it a preferred choice for components like radiators and cooling pipes in refrigerators.
Copper has a density 8.96. Its melting point is 1083.3 degrees C. and boiling point is 3567 degrees C. It is a very ductile and malleable material. This makes it ideal for forming into various shapes including in thin wires, pipes, and sheets.
