Question

C. The nuclides with odd number of both
protons and neutrons are the least stable.
Why?​

Answer 1

Answer:

The nuclides with an odd number of both protons and neutrons are the least stable because an odd number of protons and neutrons

Answer 2

In nuclear physics, properties of a nucleus depend on evenness or oddness of its atomic number Z, neutron number N and, consequently, of their sum, the mass number A. Most importantly, oddness of both Z and N tends to lower the nuclear binding energy, making odd nuclei generally less stable
