Question

Which of the following statements best describes the relationship between atoms and conductivity?(1 point)

Responses

Atoms with a nearly empty valence shell make good conductors.


Atoms with many electrons make good insulators.


Atoms with a full valence shell make good conductors.


Atoms with few electrons make good conductors.

Answer 1

Atoms with a nearly empty valence shell make good conductors.

Step-by-step explanation:

Conductivity is determined by the ability of electrons to move through a material. Atoms with a nearly empty valence shell, such as in metals, make good conductors because they have free electrons that can easily move through the material. These free electrons can carry electric charge and create conductivity. On the other hand, atoms with a full valence shell do not have free electrons and therefore do not make good conductors. Therefore, the statement that atoms with a nearly empty valence shell make good conductors is the best description of the relationship between atoms and conductivity.
