The correct Answer is:
To find the energy required to remove a neutron from \( O^{17} \), we can use the concept of binding energy. The binding energy of a nucleus is the energy required to disassemble it into its constituent nucleons. ### Step-by-Step Solution: 1. **Identify the Binding Energies**: - The binding energy per nucleon of \( O^{16} \) is given as \( 7.97 \, \text{MeV} \). - The binding energy per nucleon of \( O^{17} \) is given as \( 7.75 \, \text{MeV} \). 2. **Calculate the Total Binding Energy**: - The total binding energy of \( O^{16} \) (which has 16 nucleons) can be calculated as: \[ BE_{O^{16}} = 16 \times 7.97 \, \text{MeV} = 127.52 \, \text{MeV} \] - The total binding energy of \( O^{17} \) (which has 17 nucleons) can be calculated as: \[ BE_{O^{17}} = 17 \times 7.75 \, \text{MeV} = 131.75 \, \text{MeV} \] 3. **Determine the Energy Required to Remove a Neutron**: - When a neutron is removed from \( O^{17} \), it transforms into \( O^{16} \) and the energy required to remove that neutron is equal to the difference in binding energy between \( O^{17} \) and \( O^{16} \): \[ E = BE_{O^{17}} - BE_{O^{16}} = 131.75 \, \text{MeV} - 127.52 \, \text{MeV} = 4.23 \, \text{MeV} \] 4. **Conclusion**: - The energy required to remove a neutron from \( O^{17} \) is \( 4.23 \, \text{MeV} \).
