ProfessorAluminum is fairly reactive, but it forms a protective oxide layer on its surface which prevents further corrosion. It reacts with both acids and bases, as well as with air and water, but its reactivity is generally lower than that of highly reactive metals like sodium or potassium.

Is aluminum more reactive cesium?
No, it is less reactive.
Does magnesium react with aluminium sulphate?
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
Why does aluminium has low reactivity in the reactivity series?
Aluminum is exactly as reactive as it is in the reactivity series. However, when aluminum reacts, with oxygen for instance, a thin layer of aluminum oxide builds up on the outside of the aluminum metal. This prevents more oxygen from reaching unreacted aluminum metal. This prevents the reaction from proceeding further, thus effectively protecting the aluminum metal from further reaction.
Are magnesium and calcium more reactive with oxygen in the air than is aluminum?
Yes, both magnesium and calcium are more reactive with oxygen in the air than aluminum. Magnesium and calcium readily form oxides when exposed to oxygen, while aluminum forms a protective oxide layer that prevents further reaction.
Which metal will replace aluminum in a solution of aluminum compound?
A more reactive metal, such as zinc or magnesium, can replace aluminum in a solution of an aluminum compound through a single displacement reaction due to the reactivity series. For example, if zinc is added to a solution of aluminum chloride, zinc will replace aluminum in the compound, forming zinc chloride and aluminum metal.
