Question

`He_(2)^(3)` and `He_(1)^(3)` nuclei have the same mass number. Do they have the same binding energy ?

Answer 1

Nuclei `He_(2)^(3)` and `He_(1)^(3)` have the same mass number . `He_(2)^(3)` has two proton and one neutron. `He_(1)^(3)` has one proton and two neutron. The repulsive force between protons is missing in `._(1)He^(3)` so the binding energy of `._(1)He^(3)` is greater than that of `._(2)He^(3)`
