D) 1.5 MeV
E) 1.0 MeV.
What can we say about the number of protons and neutrons as X changes to Y?
A) All protons and neutrons remain unchanged
B) A proton changes to a neutron; the combined numbber remains unchanged.
C) A neutron changes to a proton. The combined number remains unchanged.
D) In addition to one of a, b and c occurring, a tiny bit of proton or neutron (or both) is converted to kinetic energy of the final particles.
E) We don't have enough information to answer.
Please try to state why as I'm studing for my physics final tomorrow. Thank you

The X and Y refer to unspecified atomic nuclei. All initial particles are stationary. The electron's mass is beta ^+ decay) and the second isthe electron capture. The X + e^-1 right arrow Y^-1 + v For the first is positron emission ( X right arrow Y^- + e^+ + v (me) , they are particle-antiparticle pair, Consider the following two reactions: (e^-) both have the same mass (e^+) and electron.Explanation / Answer
