How liquid drop model explains nuclear fission?

How liquid drop model explains nuclear fission?

According to the liquid drop model, the nucleus is assumed to be like a drop of a liquid with certain analogies. As a result, the nucleus takes the dumbbell like shape as is shown, and due to positive charge repulsion on the two ends splits into two fragments hence, forming daughter two nuclei.

What is liquid drop nuclear model?

liquid-drop model, in nuclear physics, a description of atomic nuclei in which the nucleons (neutrons and protons) behave like the molecules in a drop of liquid. Although inadequate to explain all nuclear phenomena, the theory underlying the model provides excellent estimates of average properties of nuclei.

What is nuclear fission PDF?

a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). ○ The fission process often produces. free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.

Which of the following is predicted accurately by liquid drop model?

The major achievements of the liquid-drop model are: It helps in predicting the atomic mass of the nuclei accurately. It helps in predicting the binding energies of various nuclei accurately.

Which phenomenon is best explained by liquid drop model?

Nuclear Fission is best explained by the liquid drop model. This model compares the nucleus with liquid drops by assuming that the nucleons(proton and neutron) are similar to molecules in a liquid drop.

What are the uses of liquid drop model?

The liquid drop model is applied to describe some basic properties of atoms, homoatomic molecules, metallic clusters of atoms and fullerene molecules. Equilibrium atomic size, energy and polarizability of the atom are calculated.

What do you mean by liquid drop?

A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop.

What is nuclear energy in simple words?

Nuclear energy is the energy in the nucleus, or core, of an atom. Nuclear energy can be used to create electricity, but it must first be released from the atom.

What are the merits of liquid drop model?

1. It explains the spherical shape of most nuclei. 2. It helps to predict the nuclear binding energy and also to assess how much is available for consumption.

Who gives liquid drop model?

One of the first models that could describe the behavior of the nuclear binding energies and therefore of nuclear masses was the mass formula of von Weizsaecker (also called the semi-empirical mass formula – SEMF) published in 1935 by German physicist Carl Friedrich von Weizsäcker.
