Answer:
D
Explanation:
because in a decay series a daughter nuclei may be stable or decay itself. that starts a decay series
When a daughter nuclei from a fission reaction is unstable and continue to decay until it reaches a stable isotope. The correct option is D.
What are Isotopes?
Isotopes are defined as chemical species which have the same number of protons but differ in the number of neutrons.
It can also be said that they are the chemical species of the same element which have the same atomic number but have different mass numbers.
For Example, C12 and C14 are the isotopes of carbon elements, which have the same atomic number but different mass numbers.
Decay series is a series of decay in which a radioactive element is decomposed into different elements until it produces one stable atom.
Hence, when daughter nuclei from a fission reaction is unstable and continue to decay until it reaches a stable isotope
