Exam-style question
Try this first
In a decay process where a neutron decays into a proton and an electron, what is the significance of the emitted antineutrino?.
- A.It carries away excess charge
- B.It balances the lepton number
- C.It conserves energy
- D.It has no effect on conservation laws
Model answer
What a good answer should say
- It balances the lepton number
Explanation
Why this works
The emitted antineutrino is crucial for maintaining the balance of lepton number during the decay, as it ensures that the total lepton number remains constant before and after the decay.
