What are the chemical properties of aluminum?

Aluminum is an active metal. In dry air, the surface of aluminum immediately forms a dense oxide film about 50 angstroms thick, so that aluminum will not be further oxidized and can withstand water. But aluminum powder burns easily when mixed with air; Molten aluminum reacts violently with water; Many metal oxides can be reduced to the corresponding metal at high temperature; Aluminum is amphoteric, soluble in both strong bases and dilute acids.
