Answer :
The fundamental difference between a chemical reaction and a nuclear reaction lies in the processes and types of changes that occur at the atomic level:
1. Chemical Reaction:
- In a chemical reaction, atoms rearrange to form new chemical compounds.
- The changes involve the breaking and forming of chemical bonds between atoms, leading to the creation of different molecules.
- These reactions involve only the electrons in the outer shell of the atoms.
- Examples of chemical reactions include combustion, oxidation-reduction reactions, and acid-base reactions.
2. Nuclear Reaction:
- In a nuclear reaction, changes occur in the nucleus of atoms.
- These reactions involve the transformation of atomic nuclei, leading to the formation of different elements or isotopes.
- Nuclear reactions involve changes in the number of protons and neutrons in the nucleus, resulting in the release of large amounts of energy.
- Examples of nuclear reactions include nuclear fission and fusion processes used in nuclear power generation and atomic bombs.
In summary, the key distinction between chemical and nuclear reactions is the scale of changes: chemical reactions involve rearrangement of electrons to form new compounds, while nuclear reactions involve changes within the atomic nucleus, leading to the formation of different elements or isotopes.
