Copper:

• The chemical element copper has the atomic number 29 and the letter Cu, which comes from the Latin word cuprum.
• It is an extremely high thermal and electrical conductivity metal that is soft, malleable, and ductile.
• Pure copper has a pinkish-orange tint when it is first exposed to the air. As a heat- and electricity-conducting material, copper is also utilized for construction.
• It is also a component of several metal alloys, including cupronickel, which is used to create coins and naval hardware, and constantan, which is used in strain gauges and thermocouples for temperature measurement.
• One of the few metals that can naturally arise in a state that is immediately useable is copper (native metals).
• In various areas, this led to extremely early human use starting around 8000 BC.
• It was the first metal to be smelted from sulphide ores about 5000 BC, the first metal to be cast into a shape in a mould around 4000 BC, and the first metal to be intentionally alloyed with another metal, tin, to create bronze around 3500 BC.
• All of these firsts occurred thousands of years later.
