Redox Reaction
Oxidation is a process, which involves loss of electrons. 
It is also called deelectronation.
process in which oxidation number of an element increases. 
Classical concept of oxidation and reduction:
Oxidation
Definition : Oxidation is a chemical reaction in which
1. Addition of oxygen.
2. Addition of electronegative atom or radical to a substance. 
3. Removal of hydrogen. 
4. Removal of electropositive radical from the substance.

Electronic concept : The substance which can gain one or more electrons 
(i.e., gets reduced) is called oxidizing agent or oxidant.
Oxidizing agent: 
Classical concept :      A substance which brings oxidation is called oxidising agent.
Oxidation number concept :  A substance which is an element whose oxidation number
decreases in a chemical reaction is called oxidizing
agent.
In this process an oxidising agent itself undergoes reduction by accepting the 
electrons.
