Q.Referring the stability belt of stable nuclides, which nuclides are -β and +β emitters? Why?

Several independent factors predict whether a given nuclide will be stable or radioactive. The even/odd pairing of protons and neutrons matters a great deal: even-Z/even-N nuclides (protons paired with protons, neutrons paired with neutrons) are by far the most abundant and stable, while odd-Z/odd-N nuclides, with two separate unpaired nucleons, are …
