The Molecular-Orbital Model for Ge Shows It to Be

question 50

Multiple Choice

The molecular-orbital model for Ge shows it to be

• A)a conductor, because all the lower energy band orbitals are filled and the gap between the lower and higher bands is large.
• B)an insulator, because all the lower energy band orbitals are filled and the gap between the lower and higher bands is large.
• C)a semiconductor, because the gap between the filled lower and empty higher energy bands is relatively small.
• D)a semiconductor, because the gap between the filled lower and empty higher energy bands is large.
• E)a conductor, because its lower energy band orbitals are only partially filled.
