@Abu Marwan: Since the video is of no use, today we are talking about copper: Copper is one of the most important mineral elements that shaped the path of human civilization from ancient times to the present day, as it combines unique physical and chemical properties that have made it the backbone of modern technology. Copper is distinguished by its reddish color and its superior ability in electrical and thermal conductivity. It ranks second in the world after silver in electrical efficiency, but it outperforms it by being more available and less expensive, which made it the first choice in global power networks. The importance of copper goes beyond just being a conductive metal; It has exceptional flexibility, which allows it to be easily formed into very fine wires or thin sheets without being exposed to breakage, in addition to being naturally resistant to corrosion, as it does not rust in the traditional form of iron, but rather is covered with a protective layer known as patina that protects it from external weather factors. The uses of copper are numerous and include all aspects of daily life. In the electrical and electronics sector, copper is the basic component of electrical wires and cables, motors, generators, and printed circuit boards on which our smart devices operate. In the construction and engineering sector, it is relied upon in the manufacture of water pipes and heating systems due to its high resistance to rust and its compliance with health standards. It is also used in external architectural designs. In the world of industry, copper is not limited to its pure form, but is also included in the formation of vital metal alloys such as yellow brass, which is composed of copper and zinc, and bronze, which is composed of copper and tin. These alloys give additional hardness and high durability that suit different industrial requirements. The benefits of copper do not stop at the boundaries of industry and electricity, but rather extend to the medical and health aspects. Studies have proven that copper has natural antibacterial and antimicrobial properties, which prompted hospitals and health centers to use it to cover surfaces and handles that a
