Metals like aluminum and copper are vital in trade.
Metals are excellent conductors of electricity. They have a high number of free electrons that can move easily through the metal lattice, allowing electric current to flow with minimal resistance. Metals are also good conductors of heat. The free movement of electrons facilitates the transfer of thermal energy through the metal, making it efficient for conducting and distributing heat. Metals exhibit malleability, which means they can be easily hammered, rolled, or pressed into thin sheets without fracturing. This property arises from the metallic bonding and the ability of metal atoms to shift positions under pressure without disrupting the overall structure.
With the exception of mercury, metals are solid at normal room temperatures. They exist in a crystalline structure, with atoms arranged in a regular lattice pattern. Metals can vary in their reactivity. Some metals, such as gold and platinum, are highly unreactive and resistant to corrosion, making them valuable for use in jewelry and other applications. However, other metals, like iron and aluminum, are more prone to oxidation and corrosion in certain environments. Metals tend to be strong and durable materials. They can withstand mechanical forces and have high tensile strength, making them suitable for load-bearing structures and applications that require durability.
The combination of their various properties makes metals versatile materials. They find widespread use in construction, manufacturing, transportation, electronics, energy generation, and many other industries. Almost all metals are solid, shiny, and white-gray. They have moderate to usually high reflectivity. They are also generally highly dense, except for some, such as alkali metals. They are more malleable and flexible and have medium to high thermal conductivity. Their melting point is often high and they alloy with other metals.

Metals are ductile, meaning they can be drawn into thin wires without breaking. The ability of metal atoms to slide past each other allows for the elongation of the material under tension, enabling the production of wires and filaments. Most metals have a characteristic luster or shine on their surfaces. This property arises from the interaction of light with the free electrons in the metal, resulting in the reflection and scattering of light. Metals typically have high densities, meaning they possess a relatively large mass in proportion to their volume. This high density contributes to their strength and stability, making them suitable for structural applications.

Metals are a class of chemical elements characterized by high electrical and thermal conductivity, malleability, ductility, and luster. Typically solid at room temperature, except for mercury, metals possess a crystalline structure that facilitates electron movement, contributing to their conductivity. They exhibit metallic bonds, sharing electrons within a lattice. Metals vary in reactivity; noble metals like gold and platinum resist corrosion, while others, such as iron and aluminum, are prone to oxidation. Their strength and durability make them suitable for diverse applications across construction, manufacturing, transportation, and electronics. Metals can form alloys, enhancing their properties. They are primarily silvery, high-density solids, with some exhibiting unique characteristics like low densities or high melting points. Metals are excellent conductors of electricity and heat, attributed to their free electrons.
Malleability allows them to be shaped without breaking, while ductility enables stretching into wires. The periodic table categorizes metals into groups, including alkali, alkaline earth, transition, and precious metals. Understanding these properties is crucial for industries relying on metal trade, especially in regions like the Middle East and West Asia, where commodities like aluminum, steel, and gold are pivotal.
