Nuclear fission is a process in which the nucleus of an atom splits into two or more smaller nuclei, releasing a large amount of energy in the process. The liquid drop model is a theoretical model that describes the nucleus as a liquid drop that can be deformed and split apart.
In the liquid drop model, the nucleus is represented as a droplet of liquid with a surface tension that holds it together. When a neutron is absorbed by the nucleus, it causes the nucleus to become unstable and deform, eventually splitting into two smaller nuclei. This process releases a large amount of energy in the form of kinetic energy and gamma radiation.
Here is a diagram illustrating nuclear fission using the liquid drop model:
[Diagram: A large nucleus represented as a droplet of liquid with a surface tension. A neutron is shown being absorbed by the nucleus, causing it to deform and split into two smaller nuclei. The two smaller nuclei are shown moving apart with the release of energy in the form of kinetic energy and gamma radiation.]
This diagram visually represents the process of nuclear fission using the liquid drop model, showing how the nucleus splits into two smaller nuclei and releases energy in the process.

Liquid Drop Model of Nuclear Fission
The liquid drop model of nuclear fission treats the nucleus as a liquid droplet with negligible surface tension. According to this model, fission occurs when a heavy nucleus, such as uranium-235, splits into two lighter nuclei, such as krypton-92 and barium-141, accompanied by the release of a large amount of energy.

Steps of Fission:
1. Neutron Absorption:
- A neutron is absorbed by the nucleus, making it unstable.
2. Oscillation and Elongation:
- The nucleus oscillates and elongates like a liquid droplet.
3. Coulomb Repulsion:
- The positively charged protons in the nucleus repel each other as the nucleus elongates.
4. Saddle Point:
- The nucleus reaches a saddle point where it is about to split.
5. Splitting into Two Fragments:
- The nucleus splits into two smaller nuclei, releasing energy.
6. Neutron Emission:
- Several neutrons are emitted from the daughter nuclei as they try to stabilize.
Energy Release:
The energy released in nuclear fission comes from the difference in mass between the original nucleus and the daughter nuclei. This mass difference is converted into energy according to Einstein's equation E=mc². The energy release can be used to generate electricity in nuclear power plants.
Factors Affecting Fission:
- Neutron Energy: Slow neutrons are more likely to be absorbed by heavier nuclei, inducing fission.
- Nuclear Size: Heavier nuclei are more likely to undergo fission because they have more protons and a weaker Coulomb repulsion.
- Neutron Cross-Section: The cross-section for neutron absorption is different for different nuclei, affecting the likelihood of fission.
