Nuclear Chemist Question:

☛ A nuclear reaction is different from a chemical reaction.
☛ In a chemical reaction, atoms of the reactants combine by a rearrangement of extra nuclear electrons but the nuclei of the atoms remain unchanged.
☛ In a nuclear reaction, however, it is the nucleus of the atom which is involved.
☛ The number of protons or neutrons in the nucleus changes to form a new element itself.
"A study of the nuclear changes in atoms is termed as Nuclear chemistry".
