Metals: 1. Metals are a class of materials made up of elements from the Periodic Table with properties such as ductility, malleability, and high thermal and electrical conductivity. 2. Metals are commonly found in everyday items such as coins, jewelry, construction materials, electronics, etc. 3. Most metals are composed of one or more elements combined with other elements in a crystal lattice structure, giving them their distinct physical properties. 4. Metals can also be classified as either ferrous or non-ferrous. Ferrous metals contain iron and are magnetic, while non-ferrous metals are not magnetic and do not contain iron. 5. Metals are used in manufacturing and fabrication in a variety of ways, such as casting, forming, welding, and machining. 6. Metals are used in a wide range of industries, including automotive, construction, electronics, aerospace, and medical. 7. The most commonly used metals include aluminum, copper, iron, lead, nickel, and zinc. 8. Metals can be recycled and reused, making them an environmentally friendly material choice.
