Metal

Metals are a group of elements known for their luster, conductivity, malleability, and ductility. They are found in the Earth's crust and have been used by humans for thousands of years for various purposes.

Physical Properties of Metals

• Luster: Metals have a shiny appearance due to their ability to reflect light.
• Conductivity: Most metals are good conductors of heat and electricity.
• Malleability: Metals can be hammered or rolled into thin sheets without breaking.
• Ductility: Metals can be drawn into thin wires without breaking.
• High Melting and Boiling Points: Metals generally have high melting and boiling points.

Chemical Properties of Metals

Metals tend to form positive ions by losing electrons. They also react with non-metals to form compounds known as metal oxides, metal chlorides, etc.

Uses of Metals

Metals have a wide range of uses in various industries and everyday life. Some common uses include:

• Construction materials (steel, aluminum, copper)
• Electrical wiring and conductors (copper, aluminum)
• Transportation (steel, aluminum)
• Jewelry and decorative items (gold, silver)
• Cookware and utensils (stainless steel, aluminum)
