An unstable nuclide `(Z lt 70)` with N/P ratio less than that required for stability can attain stability by

A

`alpha`-decay

B

`beta^(-)` decay

C

K-electron capture

D

All the three

Text Solution

Verified by Experts

The correct Answer is:
D
If N/P is less than that required for stability , the nuclide can attain stability by `alpha`-decay or `beta^(+)` -decay or by K-electron capture (only if `Z gt 70`).

Unstable nuclei attain stability through disintegration. The nuclear stability is related to neutron proton ratio (n/p). For stable nuclei n/p ratio lies close to unity for elements with low atomic numbers (20 or less) but it is more than 1 for nuclei having higher atomic numbers. Nuclei having n/p ratio either very high or low undergo nuclear transformation. when n/p ratio is higher than required for stabilioty, the nuclei have the tendency to emit beta -rays. While when n/p ratio is lower than required for stability, the nucleieither emits alpha -particles or a position or capture K-electron. The order of radioactive disinigration is

Unstable nuclei attain stability through disintegration. The nuclear stability is related to neutron proton ratio (n//p) . For stable nuclei n//p ratio lies close to unity for elements with low atmoic numbers (20 or less) but it is more than 1 for nuclei having higher atomic numbers. Nuclei having n//p ratio either very high or low undergo nuclear transformation. When n//p ratio is higher than required for stability, the nuclei have the tendency to emit beta -rays. while when n//p ratio is lower than required for stability, the nuclei either emits alpha -particles or a positron or capture K -electron.
