When the atoms/compound (a/c) 'gives' away the electrons to other substance, making the overall charge of the a/c more positive. Besides that, when the reaction involves oxygen such as combustion.
C + O2 ----> CO2
In this reaction, C which is carbon is being oxidise to CO2.

oxidation is when you take away electrons so you give it a positive charge.
Al oxidized becomes Al(3+)
oxidation-reduction reaction is the moving of electrons around.
