Welcome to Lecture 2 of Atomic Structure! In this session, we discuss two of the most important historical atomic models that shaped modern chemistry: 🔹 Thomson’s Atomic Model (Plum Pudding Model) 🔹 Rutherford’s Atomic Model (Nuclear Model of Atom) 🔹 Limitations & significance of each model 🔹 Gold Foil Experiment (Geiger–Marsden experiment) 🔹 NCERT-based theory + exam-focused questions 🔹 Solved examples for NEET & JEE This lecture builds the perfect foundation for understanding Bohr’s Model, Quantum Numbers, and Electronic Configuration. ⭐ What You Will Learn in This Lecture: ✔ Structure and assumptions of Thomson’s model ✔ Why Thomson’s model failed ✔ Rutherford’s alpha-particle scattering experiment ✔ Nuclear model of atom and its limitations ✔ Step-by-step question solving (NEET/JEE level) ✔ Conceptual MCQs + theory-based questions ⭐ Who Should Watch This: 👉 NEET 2026 aspirants 👉 JEE Mains/Advanced students 👉 Class 11 CBSE, ICSE, ISC students 👉 Anyone needing strong basics in atomic structure 🔔 Don’t forget to Like, Comment your doubts & Subscribe for more Chemistry lectures! #atomicstructure #ThomsonModel #rutherfordmodel #nuclearmodel #goldfoilexperiment #class11chemistry #neetchemistry #jeechemistry #neet2026 #jee2026 #chemistrylecture #ncertchemistry #StudyWithAbhijit #physicalchemistry 🔗 Useful Links: Previous Video - Lecture - 01: https://www.youtube.com/live/T9xyMvUlfpA Lecture - 02: • Mole Concept | Class 11 (L-2) | % Composit...
