1.	Statement 1 : Proton -proton electrostatic repulsions begin to overcome attractive forces involving protons and neutrons in heavier nuclides Statement 2 : The plot of atomic number (y-axis) veruse 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.
Answer» Statement 1 is true, statement 2 is true , statement 2 is a correct explanation for statement 1 Statement 1 is true, Statement 2 is true, statement 2 is not a correct explanation for statement 1 Statement 1 is true, statement 2 is false Statement 1 is false, statement 2 is true Solution : With INCREASE in atomic no. `(Z gt 20)`, no. of NEUTRONS increases more than th eno. of protons. So a curvature is observed as SHOWN. Hence, Statement -1 is correct. The STABILITY of heavier nuclides is due to the fact that attractive FORCES between protons and neutrons overcome the proton-proton electrostatic repulsions. Hence, Statement -2 is false
