The binding energy per nucleon of   16 O is 7.97   MeV and that of   17 O is 7.75   MeV . What is the energy in MeV required to remove a neutron from   17 O ?

Correct answer

4.23

Step-by-step solution

B E per nucleon O   16 = 7.97   MeV B E per nucleon O   17 = 7.75   MeV O 17 → n 1 0 + O 16 The energy required to remove a neutron = 17 × 7.75 - 16 × 7.97 = 4.23   MeV
