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

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

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

Carbon (C) does not have any valence electrons.

Answer 1

The correct response is:

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

This is because the metallic bonding in copper allows for free movement of electrons, enabling efficient conduction of electricity. In contrast, carbon fiber, which is primarily an allotrope of carbon (like graphite), does not have the same level of conductivity as metals due to its different electronic structure and bonding characteristics.
