Its reactivity depends upon the conditions , in acids and alkalies it is highly reactive with pure water and air it is unreactive, although in reactivity series it higher than hydrogen.
Aluminium si most reactive because is vrey quick lead.
Aluminum oxide is less reactive compared to other compounds in the same group.
True. Lithium is more active than aluminum in terms of chemical reactivity. It is a highly reactive alkali metal, while aluminum is less reactive due to the protective oxide layer that forms on its surface. This difference in reactivity affects their behavior in various chemical reactions and applications.
Aluminum is placed above carbon in the reactivity series, meaning it is more reactive than carbon. It reacts with acids to release hydrogen gas and with metal oxides to produce metals. However, it is less reactive than metals like sodium and potassium.
No, magnesium cannot displace aluminum in a chemical reaction. Magnesium is less reactive than aluminum in terms of their positions in the reactivity series of metals. Therefore, when placed in a solution containing aluminum ions, magnesium will not replace aluminum from its compounds or solutions.
The rate of corrosion is directly linked to a metal's reactivity. The higher the metal in the series, the more reactive, also more susceptible to corrosion with oxygen and water. aluminum is not easy to corrode. Aluminum quickly reacts with oxygen in the air, and the oxide layer that forms protects the metal underneath from any further reaction.
Copper and zinc can react with aluminum nitrate in a displacement reaction. Aluminum being higher in the reactivity series will displace copper or zinc from their respective nitrates in the reaction.

When aluminum sulfate reacts with silver nitrate, aluminum nitrate and silver sulfate are formed. This is because the aluminum ions in aluminum sulfate replace the silver ions in silver nitrate due to the reactivity of the metals.
Carbon comes below aluminum and above zinc in the reactivity series: Potassium Sodium Lithium Calcium Magnesium Aluminium CARBON Zinc Iron Tin Lead Copper Silver Gold Platinum
When aluminum is heated in air, it reacts with oxygen to form aluminum oxide. The chemical equation for this reaction is: 4 Al + 3 O₂ → 2 Al₂O₃. This reaction is exothermic and can produce a bright flame, showcasing the reactivity of aluminum when elevated temperatures are applied.
