Oxidation is the and reduction is the oxidation is the and reduction is the gain of electrons, loss of electrons loss of oxygen, gain of electrons gain of oxygen, loss of mass gain of oxygen, loss of electrons loss of electrons, gain of electrons

Oxidation is the loss of electrons and reduction is the gaining of electrons.

Explanation:

Given the following reaction:

Na + Cl→ NaCl

For the reaction to occur Na has to give up an electron meaning it losses an electron as shown:

Na→Na+ + e-      

on the other hand, chlorine gains an electron as shown:

Cl- + e- → Cl

This implies that Na is being oxidized while Chlorine is reduced.

The two ions(Na+ and Cl-) then combine to form Sodium Chloride.
