Exam-style question
Try this first
If a particle interaction results in a total baryon number of 3 before the interaction and 2 after, what does this indicate?.
- A.Baryon number is conserved.
- B.Baryon number is not conserved.
- C.Baryons have been created.
- D.Baryons have been destroyed.
Model answer
What a good answer should say
- Baryon number is not conserved.
Explanation
Why this works
The baryon number must remain constant in a particle interaction. A change from 3 to 2 indicates that baryons have been destroyed, violating the conservation law.
