Explain Nuclear Fission and Nuclear Fusion. Answer: Nuclear Fission and Nuclear Fusion: Isotopes: Isotopes are atoms that have the same atomic number (number of protons) but different mass numbers (numbers of neutrons) or both elements having the same atomic number. are isotopes (17 Protons and 18, 20 Neutrons) Isobars: are atoms that have the same mass numbers … [Read more...] about Nuclear Fission and Nuclear Fusion

## Semi Empirical Mass Formula

What is the Semi Empirical Mass Formula? Answer: Semi Empirical Mass Formula V. Weizsäcker proposed an equation in terms of atomic mass of the nuclide and series of binding energy term in 1935. This equation is known as Semi Empirical Mass Formula or V. Weizsäcker formula. This equation contains five factors that contribute to the binding energy of nuclei i.e. Surface … [Read more...] about Semi Empirical Mass Formula

## Nuclear Liquid Drop Model

What is the liquid drop model? Write Comparison and difference between Nucleus and Liquid Drop. Answer: Liquid Drop Model The liquid drop model is one model which explains the unique properties of the nucleus. It was first proposed by George Gamow and then developed by Niels Bohr and J. A. Wheeler. According to Bohr et al., the nucleus is a drop of incompressible nuclear … [Read more...] about Nuclear Liquid Drop Model

## Nuclear Force

What is the Nuclear Force? Answer: Nuclear Force: Absorption or emission of nuclear energy occurs in nuclear reactions or radioactive decay; We call absorb energy endothermic reactions, and those that release energy are exothermic reactions. The best-known classes of exothermic nuclear change processes are fission and fusion. The powerful forces of attraction (Nuclear … [Read more...] about Nuclear Force

## Nuclear Mass Defect | Nuclear Binding Energy

What is Nuclear Mass Defect? What is Nuclear Binding Energy? Answer: Mass Defect: we know the total number of protons and neutrons as nucleons. They composed the difference between the mass of a nucleus and the sum of the masses of the nucleons of which is called the mass defect. When the nucleus formed by nucleons then it is, find that the expected mass of a nucleus is … [Read more...] about Nuclear Mass Defect | Nuclear Binding Energy
