A nuclear reaction involves the splitting of nuclei, usually producing something unstable and releasing neutrons. After a nuclear reaction, a process of emitting radiation (alpha beta and gamma) occurs for it to gain stability. There are many ways by which Nuclear reactions differ from chemical reactions. Outer-most electrons of atoms are rearranged in chemical reaction whereas nuclei is not affected i.e. nucleus is unaffected in chemical reactions, by which the structure of atomic species remains unchanged while taking part in the chemical reactions.
But in comparison with nuclear reactions the structure of nuclear changes. In nuclear reactions the number of nucleons changes which are present in the nuclei of atom. This means new atomic species are formed in nuclear reactions. This leads to a formation of new term known as atomic transformation. This term is also known as transmutation.
