1. Periodic Properties and Variations of Properties – Physical and Chemical

The chapter discusses the organization and periodic properties of elements as represented in the Periodic Table. Key concepts include periodic law, variations in atomic radii, ionization energy, electron affinity, metallic and non-metallic character, and the significance of these trends. Understanding these properties allows for predictions about the behavior of elements and their interactions in chemical processes.
