In semiconductors at room temperature,

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

Solution

In a semiconductor, at room temperature, few of the electrons in the valence band gain enough energy to jump into the conduction band whereas the others remain in the valence band. Hence, the valence band is partially empty and the conduction band is partially filled.
