Periodic Properties
Learning Time: 4-12 hours
Content: Periodic properties are a subject that examines the physical and chemical properties of elements that vary depending on their position in the periodic table. This area encompasses atomic radius, ionization energy, electron affinity, electro-negativity, metallic character, and period-group trends. The TYT focuses on fundamental trends, while the AYT focuses on chemical bonding and transition elements. The current 2025 curriculum also addresses the context of materials science and environmental chemistry. Learning this topic provides a critical foundation for understanding the reactivity of the elements.
