(a)
Interpretation:
Half of the atoms whether remain after each half-life has to be explained.
Concept Introduction:
Half-life: The time required for the concentration of a reactant to decrease to one half of its initial value.
Thus,
In the radioactive decay process the unstable isotopes loses their energy by emitting radiation in order to attain stable species. It is converted in to stable isotopes by emitting positron
(b)
Interpretation:
Half of the atoms is whether more realistic for radioactive decay has to be explained.
Concept Introduction:
Half-life: The time required for the concentration of a reactant to decrease to one half of its initial value.
Thus,
In the radioactive decay process the unstable isotopes loses their energy by emitting radiation in order to attain stable species. It is converted in to stable isotopes by emitting positron
