The complete nuclear reaction is $=X^A⟶76Y^{235}+\underset{\alpha -\text{ particle }}{3_2{\text{ He }}^4}+\underset{\beta -\text{ partide }}{⟶}{e}^0$ $+\underset{\gamma \text{-particle }}{\gamma }$ On observing the reaction, mass number of ${}^{\prime }{X}^{\prime }$ is $A=235+12+0=247$ On observing the reaction, atomic number of ${}^{\prime }{X}^{\prime }$ is $$Z=76+6-1=81$$ Hence, element ${}^{\prime }{X}^n$ is ${}_{81}{X}^{247}$,
