Question

Select the correct statements regarding metallic conduction.

• A. Happens by the movement of electrons
• B. Happens by the movement of ions
• C. Involves the transfer of matter.
• D. Does not involve any transfer of matter.

Answer 1

Answer: (A), (D)

The correct options are
A

Happens by the movement of electrons

D

Does not involve any transfer of matter.

Metallic conduction happens due to the movement of electrons and no transfer of matter is involved.

Example: Copper wire

The conduction in copper wires happens by the flow of electrons (which have negligible mass). Hence, there is no transfer of matter.
