Nuclear reactions are collisions between two atomic nuclei or one atomic nucleus and a subatomic particle that result in the production of one or more nuclides.
Alpha decay occurs when nuclei with atomic mass number greater than 200
^4_2 He known as an alpha particle
The alpha decay general equation: ^A_Z Y \rightarrow ^{A - 4} _{z - 2} Y' + ^4_2 He
When a neutron is converted into a proton, the process is known as beta decay.
The Beta decay general equation: ^{14}_{6} C \rightarrow ^{14} _{7} N + _0^{-1} \beta
Step 1: Writing the nuclear reactions
(i) \alpha - \text{ decay of } ^{226}_{88} Ra
^{226}_{88} Ra \rightarrow ^{226 - 4}_{88 - 2} Rn + ^4_2 He
^{226}_{88} Ra \rightarrow ^{222}_{86} Rn + ^4_2 He
(ii) \alpha - \text{ decay of } ^{242}_{94} Pu
^{242}_{94} Pu \rightarrow ^{238}_{92} U + ^4_2 He
(iii) \beta^{-} - \text{ decay of } ^{32}_{15} P
Gain of one proton
^{32}_{15} P \rightarrow ^{32}_{16} S + _0^{-1} e
(iv) \beta^{-} - \text{ decay of } ^{210}_{83} Bi
Gain of one proton
^{210}_{83} Bi \rightarrow ^{210}_{84} Po + _0^{-1} e
(v) \beta^{+} - \text{ decay of } ^{11}_{6} C
Loss of one proton
^{11}_{6} C \rightarrow ^{11}_{5} B + e^{+} + v
(vi) \beta^{+} - \text{ decay of } ^{97}_{43} Tc
Loss of one proton
^{97}_{43} Tc \rightarrow ^{97}_{42} Mo + e^{+} + v
(vii) Electron capture of ^{120}_{54} Xe
^{120}_{54} Xe + e^+ \rightarrow _{53}^{120} I + v
