Question

Why is copper wire a better conductor of electricity than carbon fiber?(1 point)

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

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

Copper (Cu) has no loose electrons.

Carbon (C) does not have any valence electrons.

Answer 1

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

Metals like copper have delocalized (free) electrons that move easily and carry current. Carbon fiber is covalently bonded and lacks a comparable sea of free electrons, so it conducts much less well.
