Description

Copper is a group 1B element of the fourth period of the periodic table, one of the most important heavy non-ferrous metals. Element symbol Cu, atomic number 29, relative atomic mass 63.546. Copper is solid at room temperature, and the new section is purple-red, which is easy to be oxidized when heated. Copper has excellent electrical and thermal conductivity, good corrosion resistance, low deformation resistance, and can withstand a high degree of cold deformation without breaking. It is an important heavy non-ferrous metal material, mainly used in electronics, electrical, machinery, Industrial sectors such as construction and transport. There are hundreds of copper compounds, but there are not many chemicalbooks produced on an industrial scale, the most important of which is copper sulfate pentahydrate, or cholate (CuSO4 5H2O), followed by Bordeaux mixture (Cu(OH)2 CuSO4 ), copper metaarsenite (Cu(AsO2)2), copper acetate [Cu(CH3COO)2] complex, cuprous cyanide (CuCN), cupric chloride (CuCl2), cuprous oxide (Cu2O), Copper oxide (CuO), basic copper carbonate and copper naphthenate, etc. Copper salts can be used as agricultural fungicides. Copper sulfate can be used as an emetic and as a topical antidote for yellow phosphorus burns.
