Question

What is nuclear reaction? How does it differ from Chemical reaction?

Answer 1

nuclear reaction is semantically considered to be the process in which two nuclei, or else a nucleus of an atom and a subatomic particle(such as a proton, neutron, or high energyelectron) from outside the atom, collide to produce one or more nuclides that are different from the nuclide(s) that began the process.
 
Nuclear reactions involve changes in the nucleus of atoms -- the number of protons and/or neutrons is changed. Chemical reactions do not cause any changes at all in the nucleus. Instead, in a chemical reaction, the electron clouds of atoms are interacting, and all changes are occurring with …
