An unstable nuclide with N/P ratio more than that required for stability can attain stability by

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.

A : During radioactive disintegration an alpha -particle and a beta -particle do not emit simultaneously from any nucleus. R : An alpha -particle emits from a nucleus when the N/Z ratio is less than the stability range (where N=number of neutrons and Z=number of protons in a nucleus. )

If n//p ratio is high, the nucleus tends to stabilize by :

Statements I: The fission of a heavy nucleus is always accompanied with the neutrons along with two product nuclei. Staements II: For a lighter stble nuclide, the N/Z ratio has to be slightly greater than 1.

Assertion: hnRNA is larger than mRNNA. Reason: hnRNA has no translating introns and more exons than required for translation.
