Chapter 2: Structure of Atom
This chapter explains the discovery and structure of the atom, starting from subatomic particles (electrons, protons, neutrons) to modern quantum theory. It covers early atomic models like Thomson’s and Rutherford’s, and Bohr’s model with its postulates and limitations. The dual nature of matter and radiation (de Broglie hypothesis and Heisenberg uncertainty principle) is introduced, leading to the quantum mechanical model of the atom. The chapter explains quantum numbers, types and shapes of orbitals (s, p, d), and principles governing electron arrangement – Aufbau Principle, Pauli’s Exclusion Principle, and Hund’s Rule. It concludes with the electronic configuration of elements, forming the foundation for understanding chemical behavior.

Chapter 3: Classification of Elements and Periodicity in Properties
This chapter explores how elements are classified and how their properties show periodic patterns. It covers the evolution of classification from Dobereiner’s triads and Newlands’ law of octaves to Mendeleev’s periodic table and finally the Modern Periodic Table based on atomic numbers. The chapter explains the structure of the periodic table, including groups, periods, and blocks (s, p, d, f), and describes periodic trends such as atomic radius, ionic radius, ionization energy, electron gain enthalpy, electronegativity, metallic and non-metallic character, and valency. By understanding these trends, students can predict the behavior of elements and their compounds.

📍 Topic 1: Introduction & Early Attempts at Classification of Elements
📍 Topic 2: Structure of the Modern Periodic Table
📍 Topic 3: Periodicity in Properties & Cause of Periodicity
📍 Topic 4: Periodic Trends in Properties of Elements
📍 Topic 5: Atomic Radius
📍 Topic 6: Ionization Enthalpy
📍 Topic 7: Electron Gain Enthalpy
📍 Topic 8: Electronegativity
📍 Topic 9: Anomalous Properties of Second Period Elements
