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.

Options

A. Statement-1 is true, Statement-2 is ture, 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 ture, statement-2 is false
D. Statement-2 is false, statement-2 is true

Answer

c

Explanation

In heavier nuclei , attractive forces between proton-neuttron overcome proton-proton electrostatic repulsion.
