Question
What is metallic conductivity which factor affect metallic conductivity ### What is electronic conductivity? Explain
✓
Answer
→ "Electric conductance through metals is called metallic or electronic conductance and is due to the movement of electrons."
→ The electronic conductance depends on
(i) The nature and structure of the metal
(ii) The number of valence electrons per atom
(iii) Temperature (it decrease with increase of temperature)
→ As the electrons enter at one end and exit through the other end, the composition of the metallic conductor remains unchanged of constant.
