Nuclear Fission in Nuclear Physics Nuclear fission is the disintegration of a large nucleus into two smaller nuclei by the capture of a thermal neutron. The process in which a heavy nucleus splits up into…

Nuclear Fusion in Nuclear Physics The process in which more than one light nucleus is combined together to form a relatively heavier nucleus and liberates a tremendous amount of energy, that process is called nuclear…

Nuclear Chain Reaction The chain reaction is such a process which once started the reaction continues without requiring further energy and a tremendous amount of energy is released because of the fission of all nuclei.…

Nuclear Reaction Rutherford was first able to disintegrate nitrogen nucleus by the alpha particle (4He) emitted from a radioactive substance. This was the first event of creating a nucleus by breaking artificially a nucleus. This…

Binding Energy per Nucleon We know, each atom of all the elements, except hydrogen, is composed of protons and neutrons. These are called nucleons. The total number of nucleons is called the mass number. It…

Binding Energy We know, every nucleus, except hydrogen is composed of one or more proton and neutron. These protons and neutrons are called nucleons or nuclear elements. Combining nucleons or nuclear elements to form a…

Mass Defect From the proton-neutron theory about the structure of the nucleus, we know that other than the hydrogen nucleus of atoms of all the elements are composed of proton and neutron. So, the mass…

Radio-Isotopes: Some isotopes are found that show radioactivity for a brief period of time. These are called radioisotopes. These are radioactive isotopes since they have an unstable atomic nucleus (due to the balance between neutrons…

Isotones: Those atoms which contain a same number of neutrons (N), but a different number of protons (Z), they are called isotones. They are the atom of a different element which contains the same number…

Atomic Energy: In 1905 famous scientist Albert Einstein showed that matter and energy were actually identical. Matter can be transformed into energy. If a substance of mass m is completely transformed into energy, the amount…
