Atomic Structure and Particles

The video tutorial covers the basics of nuclear physics, focusing on the atomic nucleus. It begins with an introduction to atomic physics, emphasizing the study of electrons and atoms. The tutorial then explains Rutherford's gold foil experiment, which led to the discovery of the nucleus and its size. It discusses the components of the nucleus, including protons, neutrons, and nucleons, and defines atomic and mass numbers. The concentration of mass within the nucleus is highlighted, and the video concludes with details on the charge and mass of subatomic particles.
