Question

On the basis of chemical structure which of the following solids will most easily conduct electricity?

CaF2

Cu

NaCl

FeO2

Answer 1

Answer:

Cu

Explanation:

The electrons in copper are delocalized in a "sea of electrons" therefore they move easily between atoms becoming an excellent conductor. One has to remember the valence shell of Copper is 4s1 hence its easy movement.

Answer 2

Answer: Cu will most easily conduct electricity.

Explanation:

Metals like Cu, Cupper, have a chemical structure that let electrons to flow easily through it. This chemical structure is called "metallic bond" and its characteristic of metals as you can see in the image below.
