Periodic Table Properties and Trends for Introductory Chemistry

Understanding how elements behave is the absolute foundation of mastering chemistry. This text-based course guides you through the structure of the periodic table and the underlying principles that govern elemental properties. By the end of this course, you will gain a clear, intuitive grasp of how the periodic table is organized and how to predict chemical behavior based on an element's position. What you will learn: Understand the historical development and modern structure of the periodic table including s, p, d, and f blocks; Explain the concepts of effective nuclear charge, shielding effect, and electron configurations; Analyze key periodic trends such as atomic radius, ionization enthalpy, and electron gain enthalpy; Predict chemical reactivity and electronegativity variations across periods and down groups; Apply IUPAC nomenclature rules for elements with high atomic numbers. We begin with fundamental definitions and the historical progression of classification, reading through detailed explanations of atomic structure and the periodic laws that dictate modern chemical trends. This course is designed for Class 11 students, high schoolers, and beginners starting their chemistry journey with no prior advanced knowledge required.
