Write the electronic concept of oxidation and reduction reactions.

Explanation

The process can be explained on the basis of electrons. The reaction involving loss of electron is termed oxidation
`Fe^(2+)to Fe^(3+)+e^(-)` (loss of electron - oxidation).
The reaction involving gain of electron is termed reduction.
`Cu^(2+)+2e^(-)toCu` (gain of electron -reduction)
