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
