A plot of the number of neutrons `(n)` against the number of protons `(p)` of stable nuclei exhibits upward deviation from linearity for atomic number, `Zgt 20.` For an unstable nucleus having `n//p` ratio less than 1, the possible mode `(s)` of decay is `(are)`

A

`beta^(-)`- decay (`beta` em ission)

B

orbital or K-electron capture

C

neutron emission

D

`beta^(+)`-decay (positron em ission)

Text Solution

Verified by Experts

The correct Answer is:
B, D
N/P can be increased by `beta^(+)` decay and K electron capture. In both processes number of protons decreases and number of protons increases.

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.
