Since the video isn't very useful, today we'll talk about copper: Copper is one of the most important metallic elements that has shaped human civilization from ancient times to the present day. It combines unique physical and chemical properties that have made it the backbone of modern technology. Copper is characterized by its reddish color and its superior electrical and thermal conductivity. It ranks second globally after silver in electrical efficiency, but surpasses it in terms of availability and lower cost, making it the preferred choice for global power grids. The importance of copper goes beyond its being a conductive metal; it possesses exceptional malleability, allowing it to be easily shaped into very fine wires or thin sheets without breaking. Furthermore, it is naturally resistant to corrosion, unlike iron which rusts. Instead, it develops a protective layer known as verdigris, which shields it from external weather conditions. Copper has numerous applications across all aspects of daily life. In the electrical and electronics sector, copper is a fundamental component of electrical wires and cables, motors, generators, and the printed circuit boards that power our smart devices. In the construction and engineering sector, copper is relied upon in the manufacture of water pipes and heating systems due to its high resistance to rust and compliance with health standards. It is also used in exterior architectural designs. In the industrial world, copper is not limited to its pure form; it is used in the formation of bio-alloys such as brass (composed of copper and zinc) and bronze (composed of copper and tin). These alloys provide added strength and high durability to meet various industrial requirements. The benefits of copper extend beyond industry and electricity to include the medical and health sectors. Studies have proven that copper possesses natural antibacterial and antimicrobial properties, leading hospitals and health centers to use it to cover frequently touched surfaces and handles to reduce the spread of infection. Copper also plays a vital role in the transportation sector, where the automotive industry uses
