தமிழில் CBSE 2026-2027 Grade 9 Science CH-8 | Journey Inside the Atom | Bohr's Model & Neutron

CBSE Grade 9 Science | Exploration Journey Inside the Atom explained in Tamil. In this video, we continue Chapter 8 – Journey Inside the Atom from the new CBSE Grade 9 Science (Exploration) textbook. Students will learn how Niels Bohr improved Rutherford's atomic model by introducing fixed energy levels (shells) for electrons. This lesson explains why Rutherford's model could not explain atomic stability, how Bohr's Atomic Model solved this problem, and how electrons are arranged in different shells. Students will also learn about James Chadwick's discovery of the neutron, its properties, symbol, charge, mass, and importance in explaining the mass of atoms. The lesson further discusses the role of neutrons in atomic nuclei and how their discovery opened new directions in atomic science. This session prepares students for understanding electronic configuration, atomic number, and mass number in the upcoming lessons. Topics Covered: ✔ Rutherford's Model – Limitations ✔ Bohr's Atomic Model ✔ Fixed Energy Levels (Shells) ✔ K, L, M Shells ✔ Atomic Stability ✔ James Chadwick ✔ Discovery of the Neutron ✔ Properties of Neutrons ✔ Symbol of Neutron ✔ Importance of Neutrons in the Nucleus ✔ Contributions of Neutron Discovery 🔔 Subscribe to Virutcham CBSE for simple Tamil explanations, revision videos, mini activities, chapter tests and exam preparation sessions. 📄 PDF & Notes: Join Telegram Link: https://t.me/VirutchamCBSE Keywords: CBSE Grade 9 Science Tamil Journey Inside the Atom Tamil Bohr Atomic Model Tamil Niels Bohr Tamil Bohr Model Tamil Atomic Stability Tamil Energy Levels Tamil Electron Shells Tamil K L M Shells Tamil James Chadwick Tamil Discovery of Neutron Tamil Neutron Tamil Atomic Structure Tamil Structure of Atom Tamil Exploration Science Grade 9 Tamil CBSE Science New Syllabus 2026-27 Tamil Class 9 Science Chapter 8 Tamil Journey Inside the Atom Tamil Explanation Tags: CBSE grade 9 science tamil 2026 2027 new syllabus, CBSE class 9 science chapter 8 tamil, CBSE journey inside the atom tamil, CBSE Bohr model tamil, CBSE Niels Bohr tamil, CBSE atomic stability tamil, CBSE electron shells tamil, CBSE energy levels tamil, CBSE James Chadwick tamil, CBSE discovery of neutron tamil, CBSE neutron tamil, CBSE atomic structure tamil, CBSE exploration science chapter 8 tamil, CBSE exploration science grade 9 tamil, CBSE class 9 chemistry tamil, CBSE science concepts tamil, CBSE science learning tamil, CBSE science exam preparation tamil, Virutcham CBSE science tamil, CBSE class 9 science new syllabus 2026 2027 tamil, chemistry in tamil, science in tamil, exploration science class 9 tamil Hashtags #Exploration #Grade9Science #Class9Science #TamilScience #CBSE #CBSEScience #CBSEScienceTamil #CBSEGrade9Science #CBSEClass9Science #CBSEScience2026 #CBSEScience2027 #CBSEScienceNewSyllabus #CBSEScienceChapter8 #CBSEExploration #CBSEExplorationScience #CBSEJourneyInsideTheAtom #BohrModel #NielsBohr #JamesChadwick #Neutron #AtomicStructure #ElectronShells #AtomicStability #CBSEChemistry #ChemistryInTamil #ScienceInTamil #VirutchamCBSE #VirutchamScience #ExplorationScience #Class9ScienceTamil #Grade9ScienceTamil
