Question:
Which of the following statements is incorrect?
Neutron can cause fission in nuclear reactors but proton can not
A free proton can emit β-particle
Neutron is less stable than proton
A bound proton can emit β-particle
Solution:
A free neutron is unstable (n→p+e⁻+ν). But a similar free proton decay is not possible, since a proton is (slightly) lighter than a neutron.
