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.
aluminum oxide AlO3
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.
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.
No, aluminum oxide is not metallic. But aluminum is.
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.

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.

Not rusting of aluminium; a protective layer of aluminium oxide is formed.
No, aluminum oxide is not metallic. But aluminum is.

The definition of aluminum oxide is various forms of aluminum oxide. This only occurred naturally as corundum.
No, Aluminum oxide is a pure substance.
