When the atomic valence and conductance bands overlap,
A)an insulator is created.
B)electrical flow easily occurs.
C)electrical flow is inhibited.
D)Ohm's law no longer applies.

Question

Quizplus · Accepted Answer

When the atomic valence and conductance bands overlap, electrical flow easily occurs because there is no energy gap between the two bands that electrons must overcome in order to conduct electricity. This is the defining feature of a metal, which has overlapping valence and conductance bands and therefore conducts electricity easily.
