Mark out the incorrect statement:
Mark out the incorrect statement:
- A. A free neutron can transform itself into photon
- B. A free proton can transform itself into neutron
- C. In beta minus decay, the electron originates from nucleus
- D. All of the above
Step-by-step solution
Statement A is false because a free neutron decays into a proton, electron, and antineutrino, not a photon. Statement B is false because a free proton is stable and cannot transform into a neutron due to energy and conservation laws. Statement C is true as in beta-minus decay, the electron is created from a neutron in the nucleus. Thus, since not all statements are correct, D is incorrect.
