`beta` –decay (`beta` emission)

B

orbital or K-electron capture

C

neutron emission

D

`beta^(+)` -decay(positron emission)

In most stable nuclei neutron number N and proton number Z has the relation

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.

Staements I: Light nuclei are most stable if N =Z, while heavy nuclei are more stable if N gtZ. (N rarr number of neutrons, Z rarr number of protons) Staements II: As the number of protons increases in a nucleus, the Coulomb's repulsive forece increases, which tends to break the nucleus apart. So, to keep the nucleus apart. So, to keep the nucleus stable, more number of neutrons are needed which are neutral in nature.
