Q.

In a hypothetical fission reaction

X23692Y14156+Z9236+3R

The identity of emitted particles (R) is                   [2024]

1 γ-radiations  
2 Electron  
3 Neutron  
4 Proton  

Ans.

(3)          

               Z in LHS = 92

               Z in RHS = 56 + 36 = 92

               A in LHS = 236

               A in RHS = 141 + 92 = 233
