Which of the following best describes the concept of discrete energy levels in an atom?.
- A.Electrons can occupy any energy level.
- B.Electrons can only occupy specific energy levels.
- C.Energy levels are continuous.
- D.Energy levels are irrelevant to electron behavior.
Model answer
What a good answer should say
- Electrons can only occupy specific energy levels.
Explanation
Why this works
Discrete energy levels mean that electrons in an atom can only exist in certain allowed states, not in between. This quantization of energy levels leads to the emission of specific wavelengths of light when electrons transition between these levels.
