Text Solution

AI Generated Solution

To determine which of the two nuclei, Helium-4 (He-4) or Lithium-7 (Li-7), is more stable based on their binding energies, we will follow these steps: ### Step 1: Identify the given binding energies - Binding energy of He-4: 27.37 MeV - Binding energy of Li-7: 39.3 MeV ### Step 2: Calculate the number of nucleons in each nucleus - Helium-4 has 4 nucleons (2 protons and 2 neutrons). ...
