In an alpha decay of the nucleus, the nucleus emits an alpha particle which is equivalent to \({ }_2 He ^4\) nucleus
During the beta decay of a nucleus electrons (emitted in \(\beta^{-}\)decay) and positrons (emitted in \(\beta^{+}\)) are emitted During the gamma decay of the nucleus, photons are emitted which are electromagnetic in nature
Neutrons are not emitted in any nuclear disintegration
${ }_{\mathrm{Z}}^{\mathrm{A}} \mathrm{X} \rightarrow {}_{\mathrm{Z}-1}{\mathrm{B}} \rightarrow {}_{\mathrm{Z}-3 }\mathrm{C} \rightarrow {}_{\mathrm{Z}-2} \mathrm{D}$, જ્યાં $\mathrm{Z}$ એ $X$ નો પરમાણુક્રમાંક છે. ઉપરોક્ત ક્રમમાં ક્ષય પામતા શક્ય કણો $.....$ હશે.
