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. Unstalbe substance exhibit high radioactivity due to

Unstable nuclei attain stability through disintergration. The nuclear stability is related to neutron- proton ratio `(n//p)`.`n//p` ratio for stable nuclei lies quite close to unity for elements with low atomic numbers (`20` or less) but it is more than one for nuclei having higher atomic numbers. Nuclei having `n//p` ratio either very high or low undergo nuclear transformation.
`(i)` When `n//p` ratio is higher than required for stability, the nuclei have the tendency to emit `beta`-rays, i.e. a neutron is converted into a proton.
`(ii)` When `n//p` ratio is lower than required for stability, the nuclei increase the ratio, either by emitting `alpha`-particle or by emitting a positron or by `K`-electron capture.
