The number of neutrons accompanyng the formation of `_(54)^(139)Xe` and `_(38)^(139)Xe` from the absorption of a slow neutron by `_(92)^(235)U` follow
Correct Answer - 3 since the charge in mass is only due to the emmission of `alpha`-particle, we have Number of `alpha`-particle emitted `=(234-206)/(4)=7` Now the associated decrease in atomic number...
