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 \(45^{\circ}\) 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 \(45^{\circ}\), 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 \(\beta\)-emission to produce a daughter nucleus with a lower \(\frac{n}{p}\) ratio.
For heavier nuclides, \(p-p\) repulsions start to offset the attractive forces and an excess of neutrons over protons, is required for stability
