The energy band formed by a series of energy levels having valence electrons is called as valence band. At 0 K, the electrons fulfill the energy levels in valence band initialising from lowest one.
(i) This band is always fulfilling by electron.
(ii) This is the type of maximum energy.
(iii) Electrons are not capable of enhancing energy from external electric field.
(iv) No flow of current because of such electrons.
(v) The highest power level which may be placed by an electron in valence band at 0 K is known Fermi level.
