According to molecular orbital theory,materials with completely filled bands are called
A)conductors.
B)metals.
C)semiconductors.
D)insulators.

Question

Quizplus · Accepted Answer

According to molecular orbital theory, completely filled bands are called valence bands, which refer to the highest energy level of electrons that are occupied in a material. Insulators have completely filled valence bands, which means that there are no empty energy levels available for electrons to move in response to an electric field. As a result, they do not conduct electricity well.
