    Which of the following statement is incorrect with respect to metallic or electronic conductivity?

    A) Metallic conductivity depends on the structure of metal and its charactristics.

    B) Metallic conductivity depends on the number of electrons in the valence shell of atom of metal.

    C) The electrical conductivity of metal increases with increase in temperature.

    D) There is no change in the structure of metal during electrical conduction.

    Correct Answer: C

    Solution :

    For metal, as temperature increases, resistance increases and hence conductivity decreases.
