What is an energy gap?
What is an energy gap?
- A. the space between two orbital shells
- B. the energy equal to the energy acquired by an electron passing a \( 1 V \) electric field
- C. the energy band in which electrons can move freely
- D. an energy level at which an electron can exist
Step-by-step solution
In atomic physics, an 'energy gap' commonly refers to the difference in energy between two orbital shells. This term is used to describe the energy separation between discrete atomic energy levels, where no electron states exist in the gap. Option B defines the electron volt, option C describes the conduction band, and option D describes an energy level, none of which are gaps.
