    When carbon containg combination blistered in air it forms CO2. Sulphur burnt in air configures SO2, so identical with metals. When metals burnt in air, they also form there communicate oxides. But above-named CO2 and SO2 are in gassy form but in case of metals the plane layer behaves with oxygen, establishing a railing so the oxygen can’t get to the rest of the metal, so the blaze can’t continue. If you burnt metal so that air can get interior, metal powder / dust will be dispelled in the air.

    Metals when burnt in air the creation of oxides formed hang on the nature of metal how much it is activated towards air.

    For example:

    What happens when sodium is burnt in air?

    When sodium is warmed up in air, it starts blazing with orange flame and forms a blend of sodium oxide and sodium peroxide. Sodium goes ahead burning instantly in air when warmed-up or put under a conflagration.

    What happens when Lithium is burnt in air?

    When lithium is warmed-up or burnt in air, it commences burning with red- coloured, flame and gives lithium oxide.

    What happens when Potassium is burnt in air?

    When potassium is burnt in air, it offers potassium peroxide and potassium super oxide.

    Potassium liquefy instantly when heated or put under flame.

    What happens when Aluminium is burnt in air?

    When aluminium metal is burnt in air, it incarnates aluminium oxide.

    In this response Aluminium oxide is devised as a thin coating over aluminium metal. This layer head off further oxidation of aluminium.

    What happens when Lead is burnt in air?

    When lead is burnt in air, it produces lead oxide. This lead oxide is formed established in the form of a narrow layer over lead metal.

    What happens when Iron is burnt in air?

    When iron fillings are smoulder in air, it burns strenuously with powder in the flame of burner. Iron rod gets balmy only when burnt in air. Iron does not retaliate with oxygen attending in air and do not react with oxygen even on warming.
