Exam-style question
Try this first
Interpret the following atomic energy-level diagram and describe the transition of an electron from level 3 to level 2.
Model answer
What a good answer should say
- When an electron transitions from energy level 3 to energy level 2, it emits a photon with energy equal to the difference between these two levels.
- This emission corresponds to a specific wavelength of light, which can be observed in the atomic spectrum.
Explanation
Why this works
This answer demonstrates an understanding of energy levels and photon emission, testing the ability to interpret energy-level diagrams. It shows how energy is released during electron transitions, linking theory to observable phenomena.
