Interpretation:
Stable nuclide has to be identified among the given nuclides and explained.
Concept Introduction:
Nuclear stability means that the nucleus is stable meaning that it does not spontaneously emit any kind of radioactivity.
Nuclear stability can be explained based on neutron to proton ratio (N/Z) in the nucleus.
For a stable atoms having low
For a stable nucleus N/P ratio is one and which lies in the belt of stability of graph of number of protons to number neutrons.
When an isotope is above the belt of stability, N/P ratio is high and there exists a beta emission to decrease the stability.
