Periodicity & Periodic Trends Explained | Why Do They Occur? | Class 11 Chemistry L4

Welcome to Kaizen Tuition! 🎓 In this short Class 11 Chemistry lesson, we explore the concept of periodicity and periodic trends from the chapter Classification of Elements and Periodicity in Properties. 📚 Topics covered in this video: What is periodicity? What are periodic trends? Why do periodic trends occur? Nuclear charge and its role in periodic properties Shielding effect and its influence on outer-shell electrons How these factors affect atomic size and other periodic properties 🎯 Why watch this video? Understand the basic concepts behind periodic trends instead of simply memorising them. This foundation will help you learn atomic radius, ionic radius, ionization enthalpy, electron gain enthalpy and electronegativity.
