What are Metals?

Metals are a group of elements that have certain characteristics in common. They are typically shiny, malleable, ductile, and good conductors of heat and electricity. They are found on the left side of the periodic table and have properties that make them useful in various applications.

Physical Properties of Metals

• Shininess: Metals have a lustrous appearance, reflecting light in a characteristic way.
• Malleability: Metals can be hammered or pressed into different shapes without breaking.
• Ductility: Metals can be drawn into thin wires without breaking.
• Conductivity: Metals are good conductors of heat and electricity.
• High Melting Point and Density: Most metals have high melting points and densities compared to nonmetals.

Chemical Properties of Metals

• Reactivity: Metals can react with other elements to form compounds through processes such as oxidation and corrosion.
• Alloy Formation: Metals can be combined to form alloys with enhanced properties, such as increased strength or resistance to corrosion.

Uses of Metals

Metals are used in various industries and everyday applications. Some common uses include:

• Building materials (e.g., steel, aluminum)
• Electrical wiring and components (e.g., copper, silver)
• Transportation (e.g., cars, airplanes made of steel, aluminum)
• Cookware and utensils (e.g., stainless steel, copper)
• Jewelry (e.g., gold, silver)
