CBSE Class 11 Chemistry Chapter 2 focuses on the structure of atoms and molecules. It delves into the atomic structure, covering topics such as subatomic particles (protons, neutrons, and electrons), electronic configuration, quantum numbers, and the arrangement of electrons in atoms. The chapter also introduces the concept of chemical bonding, including ionic, covalent, and metallic bonds, as well as intermolecular forces. Understanding this chapter is crucial as it lays the groundwork for comprehending the behavior of elements and compounds in chemical reactions, which are further explored in subsequent chapters of the curriculum.
