Nuclear Chemistry
- Nuclear chemistry is the one of the branches of chemistry that deals with the study of the nucleus in an atom.
- A nuclear reaction is different from a chemical reaction.In a chemical reaction, atoms of the reactants combine by a rearrangement of extranuclear electrons but the nuclei of the atoms remain unchanged. an atom which is involved.
- The number of protons or neutrons in the nucleus changes to form a new element. A study of the nuclear changes in atoms is termed Nuclear Chemistry.
- The initial progress in this branch was done by Pierre Curie and Marie Curie by isolating natural radioactive elements and investigating their properties.
- The phenomenon of spontaneously and continuously emitting active radiation is called radioactivity and the substance emitting such radiation is called radioactive.
- The spontaneous breaking down of the unstable atoms is termed radioactive disintegration of radioactive decay. A nuclear reaction is one which proceeds with a change in the composition of the nucleus so as to produce an atom of a new element.
- The nuclear reaction is represented by an equation indicating the nuclear characteristics of the reactants and the products as The conversion of one element to another by a nuclear change is called transmutation.

Frequently Asked Questions
What is nuclear chemistry used for?
- Nuclear chemistry is used in nuclear reactors in which nuclear reactions are generated to produce energy.
- Nuclear chemistry is also used in nuclear weapons.
- Nuclear chemistry is used in biology as well. Radiations are used to treat diseases like cancer.
Is Nuclear Chemistry hard?
The basics of nuclear chemistry isn't very hard to understand. The basic reactions of nuclear chemistry known as fission and fusion can be learned easily. But, higher mechanisms of nuclear chemistry can be complex and have to be understood properly.
What are the 4 types of nuclear reactions?
- Fusion is the reaction where two light nuclei combine to create a heavier molecule and energy is released.
- Fission is the reaction where a heavy and unstable nucleus divides into two lighter nuclei and releases energy.
- Nuclear decay is emission of radiation from an unstable atom resulting in a change of nucleus into one or more other elements.
- Nuclear transmutation is the process when atomic nuclei bombard with neutrons or other particles, it results in formation of isotopes or new atoms.
How is nuclear energy being used today?
Nuclear energy has many uses in various fields. It is majorly used for electricity generation. About 10% of the world’s electricity comes from nuclear reactors. Many countries use nuclear energy in research reactors for production of medical and industrial isotopes. Nuclear chemistry is also used in agriculture.
