Answer: α particle
Explanation:-
A nuclear fission reaction is defined as the reaction in which a heavy nucleus splits into small nuclei along with release of energy.
The given reaction is
Now, as the mass on both reactant and product side must be equal:
To calculate A:
Total mass on reactant side = total mass on product side
238 = 234 + A
A = 4
To calculate Z:
Total atomic number on reactant side = total atomic number on product side
92 = 90 + Z
Z = 2
The particle with atomic number of 2 and mass number of 4 is particle.
