9.1 & 9.2 PROPERTIES OF GROUP 1 AND GROUP 17 ELEMENTS |9.3 GROUP PROPERTIES OF TRANSITION ELEMENTS

Assalamu Alaikum Students! 🌟 Welcome to Passionate Brains – where we make Chemistry simple, clear, and powerful for Class 9 students. In this complete lecture, we cover Chapter 9 – Group Properties in the Periodic Table in a detailed and easy way. This video explains the properties and trends of Group 1 (Alkali Metals), Group 17 (Halogens), and Transition Elements (d-block elements) with proper reactions, examples, and real-life applications. 📘 In This Video You Will Learn: 🔹 Why elements in the same group have similar properties 🔹 Electronic configuration and valence electrons 🔹 Atomic size and reactivity trends down the group 🔹 Reactions of Alkali Metals with water, oxygen, and chlorine 🔹 Why reactivity increases in Group 1 but decreases in Group 17 🔹 Properties and oxidising power of Halogens 🔹 Displacement reactions explained clearly 🔹 Oxidation and Reduction (Redox) with simple examples 🔹 Hydrogen halides and bond strength trend 🔹 Properties of Transition Elements 🔹 Catalytic role of transition metals 🔹 Haber Process (Ammonia manufacture) 🔹 Contact Process (Sulphuric acid manufacture) 🔹 Catalytic converter and hydrogenation of oils 🔹 Tensile strength explained in simple words This lecture is perfect for: ✔ Class 9 Chemistry students ✔ Punjab Board / FBISE / All Boards ✔ MCQs, short questions, and long questions preparation ✔ Strong concept building for exams If you want clear concepts instead of rote learning, this lecture is for you. 📌 Subscribe to Passionate Brains for complete Chemistry lectures from Class 9 to 12. #PassionateBrains #ChemistryClass9 #Chapter9Chemistry #GroupProperties #PeriodicTable #AlkaliMetals #Halogens #TransitionElements #RedoxReactions #HaberProcess #ContactProcess #PeriodicTrends #BoardExamPreparation #Class9Chemistry #ChemistryLecture
