Here is the answer. I hope u find it useful :)
Na metal is obtained by electrolysis of its molten chloride (i.e.) NaCl.
Molten NaCl is taken and two electrodes, anode and cathode, are dipped into the liquid.
Current is passed through the liquid and electrolytic reduction (decomposition) takes place as follows:
2NaCl ⇒ 2Na + Cl2
2Cl + 2e ⇒ 2Cl-
2Na+ + 2e ⇒ 2Na
The two Cl ions lose one electron each and form a covalent bond and Cl2 atom.
The Two Sodium ions gain the electrons lost by the chlorine ions and forms Na metal
