Question

Write nuclear reaction equations for :
(i) $\alpha$ - decay of ${}_{88}^{226}Ra$ (ii) $\alpha$ - decay of ${}_{94}^{242}Pu$(iii) ${\beta }^{-}$ - decay of ${}_{15}^{32}P$ (iv) ${\beta }^{-}$ - decay of ${}_{83}^{210}Bi$(v) ${\beta }^{+}$ - decay of ${}_6^{11}C$ (vi) ${\beta }^{+}$ - decay of ${}_{43}^{97}Tc$(vii) Electron capture of ${}_{54}^{120}Xe$

Answer 1

(i) ${}_{88}^{226}Ra\to {}_{86}^{222}Rn+{}_2^{4}He$

(ii) ${}_{94}^{242}\text{Pu}{\to }_{92}^{238}\text{U}{+}_2^4\text{He}$

(iii) In ${\beta }^{-1}$ decay, there is a gain of one proton and an anti-neutrino is emitted from nucleus.

${}_{15}^{32}P\Rightarrow {}_{16}^{32}S+e^{-}+\overline{\nu }$

(iv) In ${\beta }^{-}$ decay, there is a gain of one proton and an anti-neutrino is emitted from nucleus.

${}_{83}^{210}Bi\Rightarrow {}_{84}^{210}Po+e^{-}+\overline{\nu }$

(v) In ${\beta }^{+}$ decay, there is loss of one proton and an neutrino is emitted from nucleus.

${}_6^{11}C\to {}_5^{11}B+e^{+}+\nu$

(vi) In ${\beta }^{+}$ decay, there is loss of one proton and an neutrino is emitted from nucleus.

${}_{43}^{97}Tc\to {}_{42}^{97}Mo+e^{+}+\nu$

(vii) ${}_{54}^{120}Xe+e^{+}\to {}_{53}^{120}I+\nu$
