Welcome to Simma Academy! Class 9 Science | Structure of Atom | Full Chapter Explanation in one shot | CBSE | ICSE | NIOS Your one-stop learning hub for CBSE & NIOS Class 9 and Class 10 Mathematics and Science. Here you will find easy explanations, solved examples, chapter-wise solutions, exam-oriented questions, and quick revision videos to boost your scores. 📘 Subjects Covered (CBSE & NIOS) In this detailed Class 9 Science video, we explain the Discovery of Charged Particles from the chapter Structure of the Atom. This lesson covers how electrons, protons, and neutrons were discovered, why these discoveries were important, and how they helped build modern atomic theory. The explanation is based on NCERT Class 9 Science Chapter 4 and is perfect for exam preparation, quick revision, and strong concept clarity. In this video, you will learn: ✔ What are subatomic particles? ✔ How J.J. Thomson discovered electrons using the cathode ray tube experiment ✔ Properties and significance of electrons ✔ How Eugen Goldstein discovered protons through canal rays ✔ Structure, mass, and charge of protons ✔ How James Chadwick discovered neutrons in 1932 ✔ Why neutrons are essential for atomic stability ✔ Difference between electrons, protons, and neutrons ✔ Key NCERT points, shortcuts, formulas, and exam tips Understanding the discovery of charged particles helps students learn how atomic models developed—from Dalton’s theory to Thomson, Rutherford, and Bohr models. These concepts also form the base for higher classes and competitive exams. This video uses simple explanations, diagrams, and real-life examples to make learning easy and enjoyable. 📚 Why This Video Is Important for Class 9 Students Covers NCERT Class 9 Science Chapter 4 in easy language Helps in mid-term exams, annual exams, and CT/PT tests Builds strong basics for Class 10 Chemistry and higher classes Useful for competitive foundations like NTSE, Olympiads, JEE, NEET basics 📝 Key Exam Points • Electrons → negative charge • Protons → positive charge • Neutrons → no charge • Cathode rays = electrons; Canal rays = positively charged particles • Scientist names: Thomson → electron, Goldstein → proton, Chadwick → neutron ✨ About SciMa Academy We provide online & offline coaching for Grades 7–10 (CBSE/ICSE/NIOS).
