Statement 1 The plot of atomic number ( Y-axis) versus number of neutrons ( x-axis) for stable nuclei shows a curvature towards X-axis from the line of 45∘ slope as the atomic number is increased.
Statement 2 Proton-proton electrostatic repulsions begin to overcome attractive forces involving protons and neutrons in heavier nuclides.
Statement 2 Proton-proton electrostatic repulsions begin to overcome attractive forces involving protons and neutrons in heavier nuclides.
Solution:
The stability relationship can be represented by a line with a slope of 45∘, i.e. the maximum stability is attained, when N=Z.
Right or the curve a radioactive nuclide would be neutron rich and would decay be β-emission to produce a daughter nucleus with a lower np ratio.
For heavier nuclides, p−p repulsions start to offset the attractive forces and an excess of neutrons over protons, is required for stability
