Metal
Metals are a group of elements known for their high conductivity, malleability, and ductility. They are typically solid at room temperature (with the exception of mercury) and have a lustrous appearance.
Physical Properties of Metals:
- Conductivity: 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 wires without breaking.
- Luster: Metals have a shiny appearance when polished.
- High melting and boiling points: Most metals have high melting and boiling points.
Chemical Properties of Metals:
Metals tend to form positive ions by losing electrons, and they generally react with acids to produce hydrogen gas.
Examples of Common Metals:
Alloys:
Metals are often combined with other elements to form alloys, which can have improved properties compared to pure metals. Examples of alloys include steel (iron and carbon) and bronze (copper and tin).
Uses of Metals:
Metals have a wide range of practical applications, including in construction, transportation, electrical wiring, and manufacturing of various products.
