Question

The amount of energy that valence electron must have in order to jump from valence band to conduction band is called as

Answer 1

Answer:

hope above question's answer is ENERGY GAP

Answer 2

The amount of energy that valence electron must have in order to jump from valence band to conduction band is called as Band-gap.

• Valence band : The valence shell of an atom represents a band of energy. valence electrons of valence shell of the atom are confined to that band. and hence, this band is known as valence band.
• conduction band : When an electron of valence shell acquires enough amount of energy, it leaves valence shell and become a free electron and exists in specific band is known as conduction band.

Band-gap : The amount of energy required to move a valence electron from valence band to conduction band is known as band-gap.

it is the difference of energy between conduction band and valence band.

Hence the correct answer must be band-gap.
