If an atom’s outer shell of electrons is tightly bound to the nucleus, the substance is a good conductor.

Answer 1

If an atom’s outer shell of electrons is loosely bound to the nucleus, the substance is a good conductor. As electrons carry charge, a substance with loosely bound electrons allows for easy movement of electrons, resulting in good conductivity. Conversely, a substance with tightly bound electrons will not allow for easy movement of electrons, resulting in poor conductivity. The charge of the nucleus does not necessarily determine conductivity.
