The band holding the valence electrons is called the:
AValence band
BForbidden gap
CImpurity band
DJunction band
Answer & Solution
Correct answer: A. Valence band
1. Electrons in a solid occupy allowed energy bands.
2. The outermost electrons of each atom fill one of them.
3. That is the valence band.
4. So the answer is valence band.
