Metal

Metal is a type of material characterized by its ability to conduct electricity and heat, as well as its luster, malleability, and ductility. Metals are typically solid at room temperature and have high melting and boiling points.

Properties of Metals

• Conductivity: Metals are good conductors of electricity and heat due to the free movement of electrons within their structure.
• Luster: Most metals have a shiny appearance due to their ability to reflect light.
• Malleability: Metals can be hammered or rolled into thin sheets without breaking.
• Ductility: Metals can be drawn into thin wires without breaking.
• Strength: Metals are generally strong and have high tensile strength.
• Hardness: Metals can range from soft (e.g., lead) to very hard (e.g., titanium).
• High Melting and Boiling Points: Most metals have high melting and boiling points compared to non-metals.
