What Does Aluminum React With? A Comprehensive Guide


Aluminum is a versatile and widely used metal that has many unique properties. It is strong, lightweight, and corrosion resistant, making it an ideal material for many applications. It is also reactive, meaning it can interact with different elements to form compounds. In this article, we will explore what aluminum reacts with and how its reactivity is affected by temperature and pressure.

Investigating the Chemical Reactions of Aluminum: What Does it React With?

The chemical reactions of aluminum are determined by its oxidation state. Aluminum generally exists in its +3 oxidation state, which means it is highly reactive and can easily form compounds with other elements. Common reactions of aluminum include combining with oxygen to form aluminum oxide (Al2O3), combining with chlorine to form aluminum chloride (AlCl3), and combining with sulfur to form aluminum sulfide (Al2S3).

The reactivity of aluminum is also affected by temperature and pressure. At higher temperatures, aluminum is more reactive and can combine with more elements. At lower temperatures, it is less reactive and will not combine with certain elements. Pressure also affects the reactivity of aluminum, as increased pressure increases its reactivity and vice versa.

Exploring the Corrosion Resistance of Aluminum: What Does it React With?

Aluminum is well known for its corrosion resistance due to its protective layer of aluminum oxide. This layer is formed when aluminum reacts with oxygen, forming a hard and durable surface that prevents further corrosion. The thickness of this layer depends on the environment and can vary from 1-10 microns. This protective layer is effective against most acids, alkalis, and salt solutions, making aluminum an ideal choice for outdoor applications.

Compared to other metals, aluminum is much more resistant to corrosion. Steel, for example, is highly susceptible to rusting, while aluminum is not. This makes aluminum a better choice for applications where corrosion is a concern, such as marine environments or chemical plants.

Understanding the Properties of Aluminum: What Does it React With?

The properties of aluminum determine its reactivity with different elements. Its atomic structure consists of two electrons in its outermost shell, which make it highly reactive and prone to forming bonds with other elements. It forms strong covalent bonds with oxygen, chlorine, and sulfur, as well as ionic bonds with metals such as sodium and magnesium. Additionally, aluminum is able to form hydrogen bonds with water molecules, which makes it soluble in water.

The strength of aluminum’s bonds also determines its reactivity. Stronger bonds require more energy to break, so aluminum is less likely to react with elements that form stronger bonds. This is why aluminum is less reactive than other metals such as copper and magnesium.

Examining the Reactivity of Aluminum: What Does it React With?

Aluminum’s reactivity is determined by its oxidation state. Aluminum exists in its +3 oxidation state, which is the highest possible oxidation state for a metal. This means that aluminum is highly reactive and can easily form bonds with other elements. Additionally, aluminum is more reactive at higher temperatures and under increased pressure.

Aluminum’s oxidation state also determines the types of reactions it undergoes. Aluminum is able to form both single and double displacement reactions, as well as redox reactions. Single displacement reactions involve the exchange of one element for another, while double displacement reactions involve the exchange of two elements. Redox reactions involve the transfer of electrons between two species.

Analyzing the Interaction of Aluminum with Other Elements: What Does it React With?

The interaction of aluminum with other elements is largely determined by the element’s charge and the degree of polarization. The charge of the element affects the strength of the bond formed between aluminum and the element, while polarization affects the ability of the element to form a bond with aluminum. Polarized elements are more likely to form strong bonds with aluminum, while non-polarized elements are less likely to do so.

For example, aluminum is strongly attracted to oxygen due to its high polarization, while it is weakly attracted to carbon due to its low polarization. Aluminum is also strongly attracted to metals such as sodium and magnesium due to their positive charges, but is weakly attracted to noble gases such as helium and neon due to their neutral charges.


In conclusion, aluminum is a highly reactive metal that can form strong bonds with many elements. Its reactivity is primarily determined by its oxidation state and the degree of polarization of the element it is reacting with. Temperature and pressure also affect aluminum’s reactivity, with higher temperatures and pressures increasing its reactivity. Additionally, aluminum is highly corrosion resistant due to its protective layer of aluminum oxide, making it an ideal choice for many applications.

Through this article, we have gained a better understanding of aluminum’s reactivity and its interaction with other elements. We have explored how temperature and pressure affect aluminum’s reactivity, as well as its corrosion resistance. We have also examined aluminum’s bonds with different elements and analyzed the effects of polarization on its reactivity. All of this information has provided us with a comprehensive understanding of what aluminum reacts with.
