Exam-style question
Try this first
Describe the quark changes that occur during beta decay.
Model answer
What a good answer should say
- In beta decay, a neutron is transformed into a proton, emitting a beta particle (electron) and an antineutrino.
- This process involves the conversion of a down quark into an up quark within the neutron.
Explanation
Why this works
This answer demonstrates an understanding of the quark composition of particles and the specific changes that occur during beta decay, aligning with the learning objective. It tests the student's ability to apply knowledge of quarks in a nuclear process.
