Responses

Copper (Cu) has no loose electrons.
Copper (Cu) has no loose electrons.

Carbon (C) does not have any valence electrons.
Carbon (C) does not have any valence electrons.

Copper (Cu) is a metal, and only metals can conduct electricity.
Copper (Cu) is a metal, and only metals can conduct electricity.

The electrons in copper (Cu) are loosely bound to the nucleus.

Answer 1

The correct response is:

The electrons in copper (Cu) are loosely bound to the nucleus.

This statement correctly highlights that the structure of copper allows for the easy movement of electrons, which is essential for electrical conductivity. Other options are either inaccurate or misleading. For instance, copper does have loosely bound electrons that facilitate conductivity, while carbon can have valence electrons but does not conduct as well due to its non-metallic nature. Additionally, while metals are generally good conductors, there are other conductive materials that are not metals.
