Electrical and thermal conductivity in metals ________
A)is explained by a dipolar coupling model.
B)is explained by band theory.
C)is explained by matrix isolation techniques.
D)is explained by temporary ionization.
E)is a function of the level of contamination by excess electrons.

Question

Quizplus · Accepted Answer

The band theory explains the electrical and thermal conductivity in metals. According to this theory, metals have a partially filled valence band, and a conduction band that is partially filled or completely empty. The electrons in the valence band contribute to the metallic bonding, while those in the conduction band are free to move and carry electrical and thermal energy.
