Interpretation:
When Rn-222 undergoes alpha decay consecutively, the nucleus A and nucleus B formed has to be identified.
Concept Introduction:
Radioactive nuclides undergo disintegration by emission of radiation. All the radioactive nuclide do not undergo the decay at a same rate. Some decay rapidly and others decay very slowly. The nuclear stability can be quantitatively expressed by using the half-life.
The radioactive decay occurs till a stable nucleus is formed. Radioactive series is a decay process that occurs in series which begins with the long-lived radionuclide and ends up with nuclide having less
The radioactive decay can take place by alpha emission, beta emission or gamma ray emission. Alpha emission is a process in which an alpha particle is emitted. This results in the formation of nuclide of different element that has atomic number that is 2 less and mass number that is 4 less than the original nucleus. Beta emission is a process in which a beta particle is emitted. This produces a nuclide of different element similar to that of alpha particle decay. The mass number is same as that of parent nuclide while the atomic number increases by 1 unit. Gamma ray emission is a process in which the unstable nucleus emits gamma ray. This occurs along with alpha or beta emission. The gamma rays are not shown in the
