When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly.

Magnesium metal is very reactive, when stored it reacts with Oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents reaction between magnesium and oxygen in air. This is why should magnesium ribbon be burnt before burning in air.
