Question

Define Nuclear Reaction?

Answer 1

In nuclear physics or chemistry, a nuclear reaction is considered to be the process in which two nuclear particles interact to produce two or more nuclear particles.

Answer 2

Heyy frnd
Here is ur answer
a process in which the nucleus of an atom is changed by being split apart or joined with the nucleus of another atom.
________________
I have an other answer:-
In nuclear physics, a nuclear reaction is a process in which two nuclei or nuclear particles collide, to produce different products than the initial particles.

In principle a reaction can involve more than two particles colliding, but such an event is exceptionally rare.

If the particles collide and separate without changing, the process is called an elastic collision rather than a reaction.

A nuclear reaction can be represented by an equation similar to a chemical equation, and balanced in an analogous manner.
