Differences between nuclear reactions and chemical reactions??

1.	Differences between nuclear reactions and chemical reactions??
Answer» \tChemical ReactionNuclear ReactionChemical reaction normally occurs outside the nucleus.Nuclear reaction happens only inside the nucleus.When chemical reactions occur elements hold their identity and the nuclei of atoms also remains unchanged.During nuclear reactions, the nuclei of atoms changes completely and new elements are formed.Chemical reaction can be influenced by pressure or temperature.Nuclear reaction is independent of such factors.During such reactions there is low energy change.Energy changes accompanying nuclear reactions are relatively higher and larger.There is breaking of old bonds and formation of new chemical bonds in a chemical reaction.No such activity is involved during nuclear reactions.Chemical reactions can either be reversible or irreversible.Nuclear reactions are mostly irreversible.\t
