Hi, I’m Avinto, and in this section, we’ll explore the fascinating world of Nuclear Physics. The nucleus is the dense, central part of an atom, and understanding its structure is essential for exploring phenomena like radioactivity and nuclear reactions. We’ll discuss the structure of the nucleus, how to calculate the half-life and decay constant of a radioactive substance, and the relationship between nuclear mass and binding energy. We’ll also look at the differences between stable and unstable nuclei, the uses and hazards of radioisotopes, and the processes of fission and fusion. Finally, we’ll explore the operation of nuclear reactors, which harness the energy from nuclear reactions.
