Aluminium forms the oxide Al2O3, often called alumina or corundum.
It is a hard substance. Chemically it is classed as amphoteric because it reacts with acids and bases. It forms on the surface of aluminium very rapidly and passivates the surface. Aluminium is actually a reactive metal but because ot the invisible, thin oxide layer appears quite inert; without the layer aluminium would react with water to generate hydrogen.

What is the formula for the ionic compound that is formed from aluminum and oxygen?
aluminum oxide AlO3
Does ammonia react with aluminum oxide?
Yes ammonia can react with aluminum oxide. Aluminum oxide is ampoteric, that is, it shows both acidic and basic characters. Ammonia is basic in nature, so there will be a reaction between acidic and basic chemicals.
What is name of the compound Al2O3?
Al is the symbol for Aluminum and O is the symbol for oxygen. When oxygen is paired in a compound, it is changed to oxide. The name then is aluminum oxide.
Is aluminum oxide metallic?
No, aluminum oxide is not metallic. But aluminum is.
Does aluminum naturally occur?
Aluminum is abundant in the earth's crust, however it does not occur by itself in nature. All of the aluminum in nature is found combined with another element or compound.
What is the formula for the ionic compound that is formed from aluminum and oxygen?
aluminum oxide AlO3
What compound is formed when aluminum nitrogen and oxygen are added together?
aluminium nitrate

Why is gold found as gold metal but aluminium is found as aluminium oxide?
Gold is a very unreactive element, so it occurs as gold metal in nature. However, aluminum is more reactive, and so it occurs in aluminum ore (aluminum oxide) in nature, not as aluminum metal.
When aluminum oxide Al2O3 is formed as the only product from aluminum and molecular oxygen the sum of the coefficients on the reactant side is?
7
What are the products of rusting aluminum?
Not rusting of aluminium; a protective layer of aluminium oxide is formed.
Is aluminum oxide metallic?
No, aluminum oxide is not metallic. But aluminum is.
What is the percent composition of the compound formed when 2.70 g of aluminum combine with oxygen to form 5.10 g of aluminum oxide?
H
Does aluminum naturally occur?
Aluminum is abundant in the earth's crust, however it does not occur by itself in nature. All of the aluminum in nature is found combined with another element or compound.
What is the definition of aluminum oxide Aluminum Oxide refers in particular to Fused Aluminum Oxide or Fused Alumina herehttpwwwiabrasivecomproductsabrasive-grains?
The definition of aluminum oxide is various forms of aluminum oxide. This only occurred naturally as corundum.
Is aluminum oxide a mixture?
No, Aluminum oxide is a pure substance.
