தமிழில் CBSE 2026-2027 Grade 9 Science CH-8 | Journey Inside the Atom | Atomic Number & Mass Number

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 chemical elements are represented using symbols, understand the importance of atomic number (Z) and mass number (A), and learn how to calculate them using the number of protons and neutrons. This lesson also explains standard atomic notation, how atomic number identifies an element, why mass number is different from atomic number, and how to solve simple textbook problems using these concepts. This session builds the foundation for understanding electronic configuration, valency, isotopes, and isobars in the upcoming lessons. Topics Covered: ✔ Symbols of Elements ✔ Dalton's Pictorial Symbols ✔ Berzelius' Modern Symbols ✔ Rules for Writing Chemical Symbols ✔ Atomic Number (Z) ✔ Number of Protons ✔ Neutral Atoms ✔ Mass Number (A) ✔ Protons and Neutrons (Nucleons) ✔ Standard Atomic Notation ✔ Difference between Atomic Number and Mass Number ✔ Solved Examples 🔔 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 Symbols of Elements Tamil Chemical Symbols Tamil Dalton Symbols Tamil Berzelius Symbols Tamil Atomic Number Tamil Mass Number Tamil Atomic Notation Tamil Standard Atomic Notation Tamil Number of Protons Tamil Number of Neutrons Tamil Nucleons Tamil Atomic Structure 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 symbols of elements tamil, CBSE chemical symbols tamil, CBSE Dalton symbols tamil, CBSE Berzelius tamil, CBSE atomic number tamil, CBSE mass number tamil, CBSE atomic notation tamil, CBSE standard notation tamil, CBSE nucleons tamil, CBSE protons and neutrons 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 #ChemicalSymbols #AtomicNumber #MassNumber #AtomicNotation #Berzelius #Dalton #AtomicStructure #CBSEChemistry #ChemistryInTamil #ScienceInTamil #VirutchamCBSE #VirutchamScience #ExplorationScience #Class9ScienceTamil #Grade9ScienceTamil
