Question

What is a valence band?

• A. The energy band formed from those energy levels of the atoms which contain the valence electrons is called the valence band
• B. The lowest unfilled energy band formed just above the conduction band.
• C. The lowest unfilled energy band formed just beside the conduction band.
• D. partially- filled band above the completely-filled lower bands

Answer 1

Answer: (A)

The energy band formed from those energy levels of the atoms which contain the valence electrons is called the valence band

Energy band is the range of energies of a group of electrons in an atom. The lowest value of that range is the energy of the lowest energy electron and highest value is that of the highest energy electron. valence band is an energy band of the electrons in the outermost orbit of an atom. Such electrons are called Valence Electrons
