Concept explainers
(a)
Interpretation:
More stable isotope from the list has to be predicted.
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 proton ratio (n/p) in the nucleus.
For a stable atoms having low
As the number of stable isotopes increases, stability of the element increases.
(b)
Interpretation:
More stable isotope from the list has to be predicted.
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 proton ratio (n/p) in the nucleus.
For a stable atoms having low atomic number, n/p ratio is close to 1. When atomic number increases n/p becomes greater than 1.
As the number of stable isotopes increases, stability of the element increases.
