2016 · Shift 1 · Q1

JEE AdvancedChemistryChemical Kinetics and Nuclear ChemistryMultiple correct+4 / −2
A plot of the number of neutrons (N) against the number of protons (P) of stable nuclei exhibits upward deviation from linearity for atomic number, Z > 20. For an unstable nucleus having N/P ratio less than 1, the possible mode(s) of decay is(are)
  1. A
    β−\beta ^-β−-decay ( β\betaβ emission)
  2. B
    orbital or K-electron capture
  3. C
    neutron emission
  4. D
    β+\beta ^+β+-decay (positron emission)
