Energy bands in solids which are either partially filled or empty are called
Correct answer: C. conduction band
- A. valence band
- B. forbidden band
- C. conduction band
- D. innermost band
Explanation
In solid-state physics, the energy bands in solids are categorized into the valence band, conduction band, and forbidden band (also known as band gap). The conduction band is the energy band where electrons can move freely, conducting electricity. It is partially filled or empty depending on the number of available electrons in the material

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
