Exam-style question
Try this first
Explain how the neutron number affects the stability of an isotope. Provide an example.
Model answer
What a good answer should say
- The neutron number affects the stability of an isotope because an imbalance between protons and neutrons can lead to instability and radioactive decay.
- For example, carbon-14, which has 6 protons and 8 neutrons, is unstable and undergoes beta decay.
Explanation
Why this works
This question assesses the ability to connect neutron number with nuclear stability. The answer is strong as it provides a clear example of an isotope and explains the relationship between neutron number and stability, demonstrating a deeper understanding of isotopes.
