Structure of Atom | Nucleus, Electron Shells, Atomic Number & Mass Number | 9th Class Chemistry

In this lecture, we explore the basic structure of the atom in a clear and simple way. You will learn about the nucleus and its components, protons and neutrons, and understand how electrons move around the nucleus in different shells. The lecture also explains the concepts of atomic number and mass number with easy examples. This topic is very important for 9th class Chemistry and helps students build a strong foundation for further chapters. Topics Covered: • Structure of atom • Nucleus of atom • Protons, Neutrons, Electrons • Electron shells and energy levels • Atomic number • Mass number • Basic examples for understanding This lecture is helpful for school students and exam preparation.
