Exam-style question
Try this first
Which of the following best describes the relationship between energy levels and photon emission?.
- A.Photons are emitted when electrons gain energy
- B.Photons are emitted when electrons lose energy
- C.Photons have no relation to energy levels
- D.Photons can only be emitted from the ground state
Model answer
What a good answer should say
- Photons are emitted when electrons lose energy
Explanation
Why this works
When electrons transition to lower energy levels, they lose energy in the form of emitted photons, which is fundamental to understanding atomic behavior.
