This video tutorial covers various aspects of nuclear chemistry, including the structure of atoms, types of radioactive decay, and the processes of nuclear fission and fusion. It explains how to calculate the number of protons, neutrons, and electrons in isotopes, and discusses the stability of elements based on neutron-to-proton ratios. The video also provides examples of nuclear reactions, such as alpha and beta decay, and explains the concept of half-life with a practical calculation.
