A plot of the number of neutrons (N) against the number of protons (P)

A plot of the number of neutrons (N) against the number of protons (P) of stable nuclei exhibits upwards deviation from linearity for atomic number, Z > For an unstable nucleus having N/P ratio less than 1, the possible mode(s) of decay is(are) –

  1. β– decay (β emission)
  2. orbital or K-electron capture
  3. (C) Neutron emission
  4. β+  decay (positron emission)
