Early Classification Attempts: (2:09 - 6:32) Dobereiner's Triads (2:09) Newlands' Law of Octaves (3:46) Mendeleev's Periodic Table: (6:32 - 9:01) Based on atomic mass, including his predictions for then-undiscovered elements using the prefix eka-. Modern Periodic Table: (9:01 - 15:24) Developed by Henry Moseley (1913), based on atomic number. It details the 18 groups and 7 periods. IUPAC Nomenclature: (15:24 - 19:43) Naming convention for elements with atomic number cap Z is greater than 100. Electronic Configuration & Blocks: (19:43 - 24:03) Distribution of electrons (s comma p comma d comma f blocks). Periodic Trends: (24:03 - 35:48) Atomic Radius & Z-effective (24:03) Ionization Enthalpy (26:55) Electron Gain Enthalpy (30:36) Electronegativity (33:18) Chemical Reactivity & Summary: (35:48 - 38:51) Discussion on periodic reactivity and key takeaways. 💡 Whether you want to learn the complete chapter, strengthen your concepts, or revise quickly before exams, this One Shot lecture will help you understand everything in one place! 👍 Don't forget to Like, Share, and Subscribe for more Class 11 Chemistry videos and complete chapter revisions! 🔔 #Class11Chemistry #ClassificationOfElements #PeriodicityInProperties #ChemistryOneShot #JEEMains #JEEAdvanced #NEET #NCERT #Class11
