Exam-style question
Try this first
An electron collides with an atom and transfers enough energy to excite the atom to a higher energy level. If the energy levels are 2.0 eV and 5.0 eV, what is the minimum energy required for this transition?.
Model answer
What a good answer should say
- The minimum energy required for this transition is 3.0 eV.
Explanation
Why this works
This question assesses the ability to calculate the energy difference between two energy levels. The answer is strong as it demonstrates the understanding of how energy levels relate to atomic transitions, highlighting the concept of excitation.
