Class 11 Chemistry: Atomic Structure | Electrons, Protons, Thomson & Rutherford Models

Explore the evolution of atomic theory in this comprehensive lesson. We track the scientific journey from Dalton’s early atomic model to the groundbreaking discoveries of electrons and protons via discharge tube experiments. The session also delves into the Thomson model of the atom and explains the significance of the Rutherford alpha scattering experiment, which shifted our understanding of the nucleus and atomic structure. This is an essential study guide for Class 11 Chemistry students. Timestamps: [00:19] Introduction to Atomic Structure and Dalton’s Atomic Theory [02:26] Discovery of Electrons (J.J.
