Interpretation:
The daughter nuclide for alpha particle decay of
Concept Introduction:
If the reaction occurs in the nucleus of an atom then it is known as nuclear reaction. These reactions are not considered as ordinary
This nuclear reaction can be represented by
The radioactive decay can take place by emission of alpha particle, beta particle or gamma ray emission. Alpha particle decay 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 particle decay 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 particle emission. The gamma rays are not shown in the nuclear equation because they do not affect balancing the nuclear equation.
