What is the Difference Between Electronic and Ionic Conduction?

The main difference between electronic and ionic conduction lies in the type of charge carriers involved in the process. Here are the key differences:

• Electronic Conduction: This is the movement of electrons from one place to another. In solid conductors like metals and semiconductors, current is due to the movement of electrons or holes, which is described as electronic conductivity. Electronic conduction is seen in materials like metals, where the outer electrons in the atoms are loosely bound and can move freely when an electric field is applied.
• Ionic Conduction: This refers to the movement of ions (anions and/or cations) from one place to another in a crystal lattice or a solutions of electrolytes. Ionic conduction involves the transfer of energy through the motion of charged atoms or molecules, rather than electrons. When an electric field is applied, the ionic charges move, creating a current.

In summary:

• Electronic conduction involves the movement of electrons.
• Ionic conduction involves the movement of ions (charged atoms or molecules).

Both methods are forms of energy transfer, but electronic conduction is generally considered more efficient because electrons in elements can move more freely when electricity is supplied.

Comparative Table: Electronic vs Ionic Conduction

Here is a table comparing electronic and ionic conduction:

Electronic conduction is the process of transferring energy in the form of an electric current through the movement of electrons, while ionic conduction involves the movement of ionic species (positively or negatively charged) in response to an ionic gradient.
