Spontaneous fission reactions – nuclear fission reactions that do not require a neutron to proceed and not induced.Nuclear Decay – It is a process through which an unstable nucleus emits radiation in order to lose energy.Only momentum and energy are transferred in this process. It is without any notable changes in the composition. Nuclear scattering processes – It involves the collision and separation of atomic nuclei.Following processes cannot be classified as nuclear reactions: Question 2: Name the processes that are not considered to be Nuclear Reactions.Īnswer: The term nuclear reaction is in use to refer to the externally induced changes brought on to atomic nuclei. A single gram of matter release approximately 90,00,00,00,000 kilojoules of energy. This missing mass is then converted into energy. In simple language, the products formed in nuclear fission and nuclear fusion always have a lower mass than the reactants. This difference in mass is attributed to nuclear binding energy which is often referred to as a mass defect. Nuclear binding energy is the energy required to hold all the protons and neutrons within the nucleus.ĭuring a nuclear reaction like fission or fusion reaction, the mass accounted for by the nuclear binding energy is released in accordance with the equation i.e., \(E = mc^2\) (energy = mass times the square of the speed of light). Question 1: Why do Nuclear Reactions Release Tremendous Amounts of Energy?Īnswer: The mass of an atomic nucleus is usually less than the sum of the individual masses of each subatomic particle that constitutes it that is protons and neutrons. It is accompanied by the emission of a high energy photon. Gamma emission occurs when an excited nucleus returns to its ground state. It is accompanied by the emission of a beta particle i.e., high-energy electron. It is a process in which an alpha particle is liberated from the parent nucleus.īeta-decay occurs when a neutron is converted into a proton. Nuclei with mass numbers greater than 200 undergo alpha decay. Other Important Types of Nuclear Reactions Subatomic particles like neutrons or protons are formed as products of these nuclear reactions. In nuclear fusion reactions, at least two atomic nuclei combine or fuse into a single nucleus. The steam is then used to rotate turbines to generate electricity. This is done by the heat produced from the nuclear reaction to convert water into steam. The energy produced from fission reactions is converted into electricity that is in use in nuclear power plants. Nuclear fission was given by the German chemists’ Otto Hahn and Fritz Strassmann. This energy is accompanied by the emission of neutrons and gamma rays i.e., photons holding huge amounts of energy that is enough to knock electrons out of atoms. This process occurs through a nuclear reaction or radioactive decay. Nuclear fission reactions give a large amount of energy. Nuclear fission is the splitting of an atomic nucleus. The various nuclear fusion reactions of light elements power the energy production of the Sun and stars. It is in fissionable materials that produce induced nuclear fission. Thou the most notable nuclear reactions are the nuclear chain reactions. A nuclear reaction is that is employed artificially is to obtain nuclear energy, at an adjustable rate and on-demand. 2 FAQs on Nuclear Reaction Introduction to Nuclear reactionĪ nuclear reaction that occurs naturally is due to the interaction between cosmic rays and matter.
