In semiconductors at a room temperature:

In semiconductors at a room temperature:
  1. the valence band is partially empty and the conduction band is partially filled
  2. the valance band is completely filled and the conduction band is partially filled
  3. the valence band is completely filled
  4. the conduction band is completely empty

Solution

In semi-conductor at a room temperature, the valence band is partially empty and the conduction band is partially filled.
