Key Points

Electrons are lost in an oxidation reaction.
Oxidation simply means a gain of oxygen and an oxidizing agent is a substance that oxidizes something.
The reduction is the gain of electrons. A reducing agent reduces something in a reaction.
As when one molecule gets reduced, another molecule gets oxidized. Most of the time, Oxidation and Reduction take place simultaneously and such a reaction is called a redox reaction.
Redox reaction example- In a reaction between hydrogen and fluorine, hydrogen is oxidized and fluorine is reduced.
