Concept explainers
Interpretation:
The state when radioactive atoms stop undergoing further radioactive decay needs to be explained.
Concept introduction:
An unstable atom has less energy to hold the particles, these particleundergo loss in energy in the form of radiation.

Answer to Problem 88A
Radioactive atoms are highly energetic in nature. But after some decay, they are quite stable and no more decay reaction can take place.
Explanation of Solution
For the stability of an atom, loss of the extra neutrons or protons is required. Due to some decays loss of electrons also takes place, the radioactive decays result in change in
In nature, lowest energy state of an atom is stable. When the radioactive atoms gain stability they do not undergo further radioactive decay.
