Question:
$H e_{2}^{3}$ and $H e_{1}^{3}$ nuclei have the same mass number. Do they have the same binding energy?
Solution:
He23 and He13 have the same mass number but the binding energy of these two nuclei is different. The binding energy of the He13 is greater than the He23 because the
number of protons and neutrons present in both the nuclei are different. He13 has one proton and two neutrons while He23 has two protons and one neutron.
