Question

Write one balanced equation each to show.
(i) Nuclear fission
(ii) Nuclear fusion
(iii) Emission of ${\beta }^{-}$(i.e., a negative beta particle).

Answer 1

Balanced Nuclear fission reaction :
${}_0^{1}n+{}_{92}^{235}U\to {}_{56}^{144}Ba+{}_{36}^{89}Kr+3{}_0^{1}n$
Balanced nuclear fusion reaction :
${}_1^{2}H+{}^3{H}_1\to {}_2^{4}He+{}_0^{1}n$
Balanced ${\beta }^{-}$ emission reaction :
${}_6^{14}C\to {}_7^{14}N+{}_{-1}^{0}e+\overline{\nu }$
where ${}_{-1}^{0}e$ is the negative beta particle and $\overline{\nu }$ is the anti-neutrino.
