Exam-style question
Try this first
Calculate the energy of a photon emitted when an electron transitions from an energy level of -3.4 eV to -13.6 eV. Use the conversion 1 eV = 1.6 x 10^-19 J.
Model answer
What a good answer should say
- The energy of the photon is 1.6 x 10^-19 J.
Explanation
Why this works
This question tests the ability to calculate photon energy using the energy difference between two levels. The calculation involves converting electron volts to joules, demonstrating understanding of energy transitions in atoms.
