One of the foremost differences between nuclear reaction and chemical reaction is related to how the response takes place in the atom. While nuclear counterreaction takes place in the atom's nucleus, the electrons in the atom are responsible for chemical reactions involving the transfer, loss or gain of shared electrons and none of it takes place in the nucleus.
Nuclear reactions include the decomposition of the core and have nothing to do with particles. When the nucleus disintegrates, it may change to another atom because of the loss of protons. In a nuclear response, the protons and neutrons react inside the core, and in chemical reactions, the electrons respond outside of the nucleus. In a nuclear response, a new element is formed.
In science, a nuclear reaction can occur, but a chemical reaction can occur also. These have many similarities. However, one difference is that the reason that a chemical reaction occurs is because of the electrons that surround the atom. The nuclear response happens within the particles and specifically inside its nucleus. In a nuclear reaction, the nucleus decomposes. The electrons do not affect anything or change.
They are not the cause of the nuclear reaction. On the other hand, in a chemical reaction, the elections are lost, gained or shared causing this reaction. They have nothing to do with the nucleus. Therefore, the main difference between a nuclear reaction and a chemical reaction has to do with where the reaction is taking place either in the nucleus or with the electrons.
