Copper is a well-known element because of its distinctive reddish metallic color and because it occurs in pure form in daily life. Here is a collection of facts about this beautiful transition metal
Atomic Number The atomic number for copper is 29 which means every copper atom contains 29 protons.
Discovery Copper has been known since prehistoric time. It has been mined for more than 5000 years. Mankind has used the metal since at least 9000 BC in the Middle East. A copper pendant dated to 8700 BC was found in Iraq. Scientists believe only iron from meteorites and gold were used by people earlier than copper.
Word Origin Latin cuprum from the isle of Cyprus which is famed for its copper mines and Old English coper and copper. The modern name copper first came into use around 1530.
Properties Copper has a melting point of 1083.4 43- 0.2C boiling point of 2567C specific gravity of 8.96 20C with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable ductile and a good conductor of electricity and heat. It is second only to silver as an electrical conductor.
Uses Copper is widely used in the electrical industry. In addition to many other uses copper is used in plumbing and for cookware. Brass and bronze are two important copper alloys. Copper compounds are toxic to invertebrates and are used as algicides and pesticides. Copper compounds are used in analytical chemistry as in the use of Fehling39s solution to test for sugar. American coins contain copper.
Sources Sometimes copper appears in its native state. It is found in many minerals including malachite cuprite bornite azurite and chalcopyrite. Copper ore deposits are known in North America South America and Africa. Copper is obtained by smelting leaching and electrolysis of the copper sulfides oxides and carbonates. Copper is commercially available at a purity of 99.99943 .
