Nuclear and chemical reaction has the following similarities:
(i)-both involve the subatomic particles; electrons, protons and neutrons in an atom
(ii)-both involve the subatomic particles trying to make the atom more stable.
(iii)-Some for of energy transfer/release/absorb from/to the environment take place.
Nuclear and chemical reaction has the following differences:
(i) Nuclear reactions mainly involve protons and neutrons in the nucleus of an atom.
Chemical reactions mainly involve outer electrons in the energy levels an atom.
(ii) Nuclear reactions form a new element.
Chemical reactions do not form new elements
(iii) Nuclear reactions mainly involve evolution/production of large quantity of heat/energy.
Chemical reactions produce or absorb small quantity of heat/energy.
(iv)Nuclear reactions are accompanied by a loss in mass/mass defect.Do not obey the law of conservation of matter.
Chemical reactions are not accompanied by a loss in mass/ mass defect hence obey the law of conservation of matter.
(v)The rate of decay/ disintegration of the nuclide is independent of physical conditions (temperature/pressure /purityp/article size)
The rate of a chemical reaction is dependent on physical conditions (temperature/pressure/purity/particle size/ surface area)
