Question

Explain how electric conduction becomes possible in metallic conductor and in electrolytic conductors.

✓

Answer

→Conductors possess mobile charge carriers. In metallic conductors, there are free electrons as electric charge carriers.
→In metal electrons in the outer most orbit Valence electrons part away from their atoms and they are free to move. These electrons are free to move within metal, but they are not free to leave metal.
→These free electrons collide with each other and with other ions, and move randomly in different directions.
→The positive ions made of bound electrons and nuclei remain held in their fixed positions.
→In electrolytic conductors, the charge carriers are both positive and negative ions, but the movement of the charge carriers is affected by both the external field as well as the chemical forces.
