Question

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

Atoms with few electrons make good conductors.

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.

Answer 1

Atoms with a nearly empty valence shell make good conductors.

Reason: Conductivity depends on how easily electrons can move. Atoms with few valence electrons (nearly empty valence shell) can donate them to form a sea of mobile electrons (metals), so they conduct well. Atoms with full valence shells are insulating.
