Aluminum, is a chemical element with the atomic number 13. It is a light, silvery-grey metal that is the most abundant metallic element in Earth's crust and the most widely used nonferrous metal. Aluminum is known for its low density, high strength, and resistance to corrosion, which makes it ideal for a wide range of applications, including in transportation, construction, and packaging. Due to its chemical activity, aluminum never occurs in the metallic form in nature but is found in compounds in rocks, vegetation, and animals. It is also present in bauxite, the principal aluminum ore, and is used in various chemicals and medicines.

One of the notable properties of aluminum is its excellent resistance to corrosion. When exposed to air, aluminum forms a thin, transparent oxide layer on its surface, which acts as a protective barrier against further oxidation. This natural oxide layer helps prevent rust and corrosion, making aluminum suitable for various applications in corrosive environments. Aluminum's combination of lightweight, strength, and corrosion resistance makes it highly versatile in numerous applications. It is commonly used in transportation (including automotive, aerospace, and marine industries), construction (for windows, doors, facades, and structural components), packaging (cans, foils), electrical wiring, machinery parts, and consumer products.

Aluminum has a face-centered cubic (FCC) crystalline structure, which allows for efficient packing of atoms and provides strength and stability. Aluminum atoms are held together by metallic bonds, where valence electrons are delocalized and shared among neighboring atoms. This bonding results in the cohesive forces that give aluminum its strength. When exposed to air, aluminum rapidly forms a thin layer of aluminum oxide (Al2O3) on its surface. This layer acts as a protective barrier, preventing further oxidation and corrosion of the underlying metal. It self-repairs if damaged, which contributes to aluminum's corrosion resistance.

Aluminum has a relatively low melting point, which enables efficient recycling processes. Recycling involves melting aluminum scrap, removing impurities, and reforming it into new products, saving energy compared to primary production. Aluminum's reactivity is mitigated by the formation of the protective aluminum oxide layer. This oxide layer quickly forms on the surface when aluminum is exposed to oxygen, preventing further reaction and corrosion.

Aluminum is not considered a toxic metal in the same way as elements like lead, mercury, or cadmium. It is a naturally occurring element and is widely distributed in the environment. In fact, aluminum is the third most abundant element on Earth's crust. The human body is exposed to small amounts of aluminum through various sources such as food, water, air, and medications. Ingesting or absorbing small quantities of aluminum is generally considered safe for most individuals, as the body has mechanisms to tolerate and eliminate it naturally.

However, excessive exposure to high concentrations of aluminum over a long period can potentially lead to health concerns. Prolonged exposure to elevated levels of aluminum has been associated with detrimental effects on certain organs, such as the lungs and kidneys, particularly in occupational settings where there may be high exposure to aluminum dust or fumes. While there have been concerns about aluminum's potential role in neurological disorders like Alzheimer's disease, the scientific community has not established a direct causal relationship. The majority of research does not support the notion that everyday exposure to aluminum from common sources, such as cookware, food packaging, or antiperspirants, contributes significantly to the development of such conditions.
