2 Mg + O2 ----> 2 [Mg2+][O2-] 
If we split the equation into its oxidation and reduction reactions we get: 
Mg ----> Mg2+ + 2 e- 
The magnesium atom loses two electrons in the above reaction, making this part of the reaction the oxidation part. 
O2 + 4 e- ----> 2 O2- 
Each oxygen molecule gains four electrons to form a pair of O2- ions, making this part of the reaction the reduction reaction.
