Question
3- Radioactivity 𝛂: A. It is accompanied by the emission of neutrinos or antinemrinos B. It is generally observed for light nuclei Z < 50 C. It is an isobaric transformation D. It is a transformation by partition E. The particle 𝛂 corresponds to an oxygen nucleus F. The particle α corresponds to a hydrogen nucleus
Solution
A. False. Alpha decay is not accompanied by the emission of neutrinos or antineutrinos. These particles are typically involved in beta decay.
B. False. Alpha decay is generally observed for heavy nuclei with atomic number Z > 83.
C. True. Alpha decay is an isobaric transformation. This means that the total number of nucleons (protons and neutrons) remains the same before and after the decay.
D. True. Alpha decay is a transformation by partition. The parent nucleus splits into two parts, one of which is the alpha particle.
E. False. The alpha particle corresponds to a helium nucleus, not an oxygen nucleus. It consists of 2 protons and 2 neutrons.
F. False. The alpha particle does not correspond to a hydrogen nucleus. As mentioned above, it corresponds to a helium nucleus.
