What is energy gap?
(a) The energy band in which electrons can move freely.
(b) An energy level at which an electron can exist
(c) The space between two orbital shells
(d) The energy equal to the energy acquired by an electron passing 1 V electric field

The energy gap is the difference between the highest occupied and the lowest unoccupied energy states in a material. It is essential in understanding electronic properties in semiconductors and insulators. Among the given options, none correctly define it, as the energy gap specifically describes the energy difference between these two states. ;

The energy gap is the difference between the highest occupied energy level and the lowest unoccupied energy level in a material, crucial for understanding conductivity. None of the provided options correctly define it. A correct focus would be on the distinction between the valence band and the conduction band, which determines a material's electrical properties.
