Marks: +1, -0
Write nuclear reaction equations for
(i) α-decay of 88226Ra{}^{226}_{88}\mathrm{Ra}
(ii) α-decay of 94242Pu{}^{242}_{94}\mathrm{Pu}
(iii) β−\beta^{-} - decay of 1532P{}^{32}_{15}\mathrm{P}
iv) β−\beta^{-} - decay of 83210Bi{}^{210}_{83}\mathrm{Bi}
(v) β+\beta^{+} - decay of 611{}^{11}_{6} C
(vi) β+\beta^{+} - decay of 4397Tc{}^{97}_{43}\mathrm{Tc}
(vii) Electron capture of 54120Xe{}^{120}_{54}\mathrm{Xe}
Solution:  
(i) 88226Ra{}^{226}_{88}\mathrm{Ra} → 86222Rn+24He{}^{222}_{86}\mathrm{Rn} + {}^{4}_{2}\mathrm{He}
(ii) 94242Pu{}^{242}_{94}\mathrm{Pu} → 92238U+24He{}^{238}_{92}\mathrm{U} + {}^{4}_{2}\mathrm{He}
(iii) 1532P{}^{32}_{15}\mathrm{P} → 132S+e−+v−{}^{32}_{1}\mathrm{S}+e^{-}+\overset{-}{v}
(iv) 83210Bi{}^{210}_{83}\mathrm{Bi} → 84210Po+e−+v−{}^{210}_{84}\mathrm{Po}+e^{-}+\overset{-}{v}
(v) 611{}^{11}_{6} C → 511B+e++v{}^{11}_{5}\mathrm{B} + e^{+} + v
(vi) 4397Tc{}^{97}_{43}\mathrm{Tc} → 4297Mo+e++v{}^{97}_{42}\mathrm{Mo} + e^{+} + v
(vii) 54120Xe{}^{120}_{54}\mathrm{Xe} + e+e^{+} → 53120I+v{}^{120}_{53}\mathrm{I} + v
