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 will most easily conduct electricity.

Step-by-step 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.

Answer 2

Cu

Step-by-step 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.
