Distinguish between a nuclear reaction and a chemical reaction.

Definition:

• A nuclear reaction is a process in which two atomic nuclei or nuclear particles collide to produce different products than the initial particles. In other words, it involves a change in the composition of the nucleus of the atom.
• A chemical reaction, on the other hand, involves making or breaking of bonds between atoms. It results in the formation of new substances with new properties. The nucleus of the atom remains unchanged.

Energy Involved:

• Nuclear reactions involve a much higher amount of energy compared to chemical reactions. This is because nuclear reactions involve changes in the nucleus of the atom, which holds a large amount of energy (according to E=mc^2).
• Chemical reactions involve relatively less energy as they only involve the electrons in the outermost shell of the atom.

Change in Elements:

• In a nuclear reaction, one element can change into another. This is due to the change in the number of protons in the nucleus during the reaction.
• In a chemical reaction, the elements remain the same. Only the arrangement of atoms changes to form new compounds.

Reaction Rate:

• The rate of a nuclear reaction is not affected by temperature, pressure, or the presence of other atoms to which the nucleus may be bonded. It is only affected by the presence of other nuclear particles.
• The rate of a chemical reaction can be influenced by temperature, pressure, and catalysts.

Conservation of Mass:

• In nuclear reactions, there is a small change in mass because mass is converted into energy.
• In chemical reactions, the law of conservation of mass applies, i.e., the total mass of the reactants equals the total mass of the products.

Definition:

• A nuclear reaction involves changes in the nucleus of an atom, which often leads to a change in the atom's atomic number, thereby transforming it into a different element. These reactions are usually associated with large energy changes.
• A chemical reaction, on the other hand, involves changes in the way that atoms are arranged to form molecules. The atoms themselves do not change, but the bonds between them do. These reactions are associated with smaller energy changes.

Energy Involved:

• Nuclear reactions involve a much larger amount of energy compared to chemical reactions. This is because nuclear reactions involve changes in the nucleus of an atom, where a large amount of energy is stored.

Particles Involved:

• In a nuclear reaction, the protons and neutrons in an atom's nucleus are involved. This can lead to the emission of radiation.
• In a chemical reaction, only the electrons of the atoms are involved. The nucleus of the atoms remains unchanged.

Change in Elements:

• In a nuclear reaction, one element can change into another. This is not possible in a chemical reaction.

Rate of Reaction:

• The rate of a nuclear reaction is not typically affected by temperature, pressure, or the presence of a catalyst.
• The rate of a chemical reaction can be influenced by factors such as temperature, pressure, and the presence of a catalyst.

Conservation Laws:

• In a nuclear reaction,
