  • Aluminum is a very reactive metal.
  • The outer surface of the metal is actually covered by a very thin layer of the oxide which keeps the metal protected from the air. But when the oxide layer is damaged, aluminum comes in contact with the air.
  • It is easily attacked by air. Then aluminium starts reacting with the oxygen. It will burn as bright white flame to change into aluminum(III) oxide.

Chemical Equation:   
4Al + 3O2 → 2Al2O3
