Copper smelting appears to have been developed independently in several parts of the world. In addition to its development in the Balkans by 5500 BC, it was developed in China before 2800 BC, in the Andes around 2000 BC, in Central America around 600 AD, and in West Africa around 900 AD.
The period of copper is 4.
The chemical symbol for copper is "Cu" and its atomic number is 29. Cu is derived from the latin Cuprum, meaning copper.
