So reactive that any aluminium surface exposed to oxygen is oxidized. There is always alumina (micro-scopic layer) on aluminium surfaces. However, that layer seals the aluminium from further oxidation so you don't get a pile of alumina from a soda can!!
Aluminum 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.
Aluminum is a highly reactive metal, despite its protective coating of oxide. If Aluminum is burned it will form Aluminum (III) oxide. Aluminum will react with halogens, acids, and bases.
A measure of reactivity is the electronegativity; in the Pauling system the value for aluminium is 1,61, a moderate reactivity.

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.
Is aluminum more reactive cesium?
No, it is less reactive.
Is chlorine more reactive than aluminum?
Yes, chlorine is more reactive than aluminum. Chlorine is a highly reactive non-metal, while aluminum is a reactive metal. Chlorine readily reacts with other elements to form compounds, whereas aluminum is relatively stable in its metallic form.
Is aluminium a most reactive metal?
Aluminum is pretty reactive, but it is nowhere near the most reactive.
Is aluminum reactive to chemicals?
Yes.
Which is the least reactive sodium aluminum or magnesium?
Aluminum is the least reactive among sodium, aluminum, and magnesium. This is because aluminum is more stable due to the presence of a protective oxide layer on its surface, which prevents further reactions. Magnesium is more reactive than both sodium and aluminum.
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
Why is carbon not used for reducing aluminum from aluminum oxide?
Carbon cannot be used for reducing aluminum from aluminum oxide because aluminum is more reactive than carbon. This means that aluminum is not easily displaced by carbon in the reduction reaction. Instead, aluminum is typically extracted from its ore using electrolysis.
Is lithium more reactive than aluminum?
Yes, lithium is more reactive than aluminum. This is because lithium is a highly reactive alkali metal that readily reacts with water and air, while aluminum is a relatively reactive metal that forms a protective oxide layer on its surface, preventing further reactions.
Which is the less reactive - aluminum or lithium?
Aluminum is less reactive than lithium. Aluminum forms a protective oxide layer on its surface that prevents further reaction, while lithium is highly reactive and can react violently with water or air.
Are aluminum and chlorine reactive?
Yes, aluminum and chlorine are reactive. When they come into contact, they form aluminum chloride, which is a white powder that can be irritating to the skin and eyes. The reaction between aluminum and chlorine is exothermic, meaning it releases heat.
Does magnesium react with aluminium sulphate?
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
Which is more reactive chlorine or aluminium?
Chlorine is more reactive than aluminum. Chlorine is a highly reactive nonmetal that readily forms compounds, while aluminum is a reactive metal that forms a protective oxide layer, reducing its reactivity compared to chlorine.
