Metals react with air to form metal oxides, a type of corrosion. The reaction is accelerated by moisture in the air. The process is called oxidation and can be seen in rust. Rust is an iron oxide, which forms when iron reacts with oxygen in the air. Other metals, such as copper, aluminum, and zinc, …
Strength: Metals are used for many structural applications because of their strength. Steel is the most common metal used for building structures. Electrical Conductivity: Metals are excellent conductors of electricity and are used in wiring and other electrical applications. Copper is the most common metal used in electrical wiring due to its high conductivity and …

The melting point of a substance is the temperature at which it changes from a solid to a liquid. The boiling point is the temperature at which a substance changes from a liquid to a gas. A good example of this is water. The melting point of water is 0°C (32°F) and the boiling point …

Metals have a distinctive sound when struck or tapped. This sound is referred to as the “sonarity” of the metal and is determined by the hardness and thickness of the material. Soft metals such as aluminum have a higher sonority than harder metals such as steel. The sonority of a metal is often used to …
Electrical conductivity of metals is the ability of a metal to carry an electrical current. Metals are generally good conductors of electricity, meaning they easily allow the flow of electric charge. Examples of metals with high electrical conductivity include copper, silver, and gold.
Thermal conductivity of metals is a measure of how well a metal conducts heat. It is a measure of the rate at which heat energy is conducted through a material. Metals generally have higher thermal conductivity than other materials such as plastics or wood. This means that metals are better at transferring heat from one …
Metallic lustre is a bright, shiny and reflective appearance that is displayed by metals. It is caused by the reflection of light off of the metal’s surface. The color of the metal’s lustre is determined by the composition of the metal and the type of surface finish applied to the metal. Examples of metals that …
In simple terms, the hardness of a metal is a measure of its resistance to scratching, abrasion, or other forms of deformation. In other words, a metal with a high hardness is more difficult to scratch or deform than a metal with a low hardness. For example, a steel nail is harder than a lead …
Ductility is the ability of a metal to be stretched or drawn into a wire without breaking. It is a measure of the metal’s malleability, or ability to be deformed without fracture. Examples of ductile metals are copper, silver, gold, and aluminum.
Malleability is a property of metals that enables them to be deformed into various shapes without breaking or cracking. It is due to the plastic deformation of their crystalline structure. Examples of malleable metals include gold, silver, copper, aluminum, lead, iron, and tin. maliability
