Answer:
Conserved
Explanation:
In balancing nuclear reaction equations, there is conservation of mass numbers and atomic numbers, i.e the sum of the mass number on the product side must be equal to the sum of mass numbers on the reactant side.
Also, the sum of the atomic numbers on the product side must be equal to the sum of the atomic numbers on the reactant side.
Note: A nuclear reaction is a process in which a nucleus reacts with an elementary particle.
