Question

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.
A. Statement 1 is true , statement 2 is true , statement 2 is a correct explanation for statement 1
B. Statement 1 is true , statement 2 is true , statement 2 is not a correct explanation for statement 1
C. Statement 1 is true , statement 2 is false
D. Statement 1 is false , statement 2 is true

Answer 1

Correct Answer - C
