* Metallic Bonding: Sodium is a metal, and metals have a unique type of bonding called metallic bonding. In this type of bonding, the outer electrons of the metal atoms are loosely held and can move freely throughout the material.

* Free Electrons: These free electrons act as charge carriers. When an electric potential is applied across a piece of sodium, these free electrons can easily flow, carrying the electric current.

Important Note: Sodium is highly reactive and readily reacts with water and air. It's not practical to use pure sodium as a conductor in everyday applications.
