Metal

Metal is a type of material that is typically hard, shiny, and malleable. It is a good conductor of heat and electricity, and it often has a high melting point. Metals are found in nature and are also produced through various industrial processes.

Physical Properties of Metals

Shiny: Most metals have a shiny appearance when freshly polished.
Conductivity: Metals are good conductors of heat and electricity.
Malleability: Metals can be hammered or pressed into different shapes without breaking.
Ductility: Metals can be drawn into thin wires without breaking.
High Melting Point: Most metals have high melting points, which make them suitable for high-temperature applications.

Chemical Properties of Metals

Corrosion: Many metals can corrode when exposed to air and moisture, forming oxides or other compounds.
Reaction with Acids: Some metals react with acids to produce hydrogen gas and a salt.
Alloys: Metals can be combined with other elements to form alloys with improved properties.

Common Metals

Some common metals include:

Uses of Metals

Metals have a wide range of uses in various industries, including:
