Observe the following statements regarding isotones i) .^(59)K_(19) and .^(40)Ca_(20) are isotones ii) Nuclides having different atomic numbers (z) and mass number (A) but same number of neutrons (n) are called Isotones iii) .^(19)F_(9) and .^(23)Na_(11) are isotones The correct answer is

Statement-1:Light nuclei having equal number of protons and neutrons are more stable Statement-2:In heavy nuclei, there is an excess of neutrons due to comlomb repulsion between protons .

Statement : The plot of atomic number ( y -axis ) versus number of neutrons ( x -axis ) for stable nuclei shows a curvature towards x-axis fron the line of 45^@ slope as the atomic number is increased . Explanation : proton -proton electrostatic repulsions begin to overcome attracive forces involving protons and neutrons in heavier nuclides.
