Exam-style question
Try this first
In a alpha beta gamma comparison, which option best applies the AQA A-Level Physics objective to use the relationship between nuclear radius and nucleon number. while keeping isotope notation, radiation type, activity and safety reasoning distinct?.
- A.nuclear-case-26: Apply Use the relationship between nuclear radius and nucleon number. in Nuclear radius.
- B.nuclear-case-26: Mix Nuclear radius with a different nuclear model and ignore the measured quantity.
- C.nuclear-case-26: Use a generic radiation phrase without isotope, activity or count-rate reasoning.
- D.nuclear-case-26: Treat Radioactivity as simple recall and omit the A-Level Physics distinction.
Model answer
What a good answer should say
- The correct option is nuclear-case-26: Apply Use the relationship between nuclear radius and nucleon number.
- in Nuclear radius.
Explanation
Why this works
It is correct because it directly supports the approved objective: Use the relationship between nuclear radius and nucleon number. The other options are weaker because they confuse radiation type, isotope structure, count-rate interpretation, half-life reasoning, shielding, contamination or irradiation with a nearby but different nuclear physics idea.
