History

Copper occurs naturally as native copper and was known to some of the oldest civilizations on record. Earliest estimates of the discovery of copper suggest around 9000 BC in the Middle East. It was one of the most important materials to humans throughout the copper and bronze ages. From the Latin word cuprum, from the island of Cyprus

Discoverers	Known to the ancients.
Discovery Location
Discovery Year
Etymology (Name Origin)	Symbol from Latin: cuprum (island of Cyprus famed for its copper mines).
Pronunciation	KOP-er (English)

Cooking acidic food in copper pots can cause toxicity

Pure copper is orange-red and acquires a reddish tarnish when exposed to air

Uses

Copper is often used for electrical wiring applications and for household plumbing applications. Copper sulfate is used as a fungicide and as an algicide in rivers, lakes and ponds. It is also used in cookware and cooking utensils. Commercially important alloys such as brass and bronze are made with copper and other metals. Most often used as an electrical conductor. Also used in the manufacture of water pipes. Its alloys are used in jewelry and for coins.

Sources

Pure copper occurs rarely in nature. Usually found in sulfides as in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides like cuprite (Cu2O).
