Answer 1

The correct response is:

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

In conductive materials, such as metals, the outer electrons are not tightly bound to their respective nuclei, allowing them to move freely. This mobility of electrons is what facilitates electrical conductivity.
