The Periodic Table and Periodicity chapter forms the foundation of Inorganic Chemistry, explaining how the arrangement of elements is linked to their electronic configuration and recurring chemical properties. This section is designed for Class 11–12 students, undergraduate learners, and competitive exam aspirants, with strong emphasis on conceptual clarity, trend analysis, and exam relevance.

In this section, you will study:

• Modern periodic law and evolution of the periodic table

• Electronic configuration of elements and its role in periodic classification

• Long form of the periodic table – blocks, periods, and groups

• Periodic trends in atomic and ionic radii

• Ionization enthalpy – factors affecting and trend analysis

• Electron gain enthalpy (electron affinity) and its exceptions

• Electronegativity scales and comparative behavior

• Valency and oxidation states across periods and groups

• Metallic and non-metallic character and periodic variation

• Diagonal relationships and anomalous behaviors

• NCERT-aligned explanations, supported by graphs, comparative tables, conceptual MCQs, and PYQs

The content is structured to build a strong logical framework, enabling students to predict chemical behavior, solve trend-based questions, and confidently handle application-oriented problems.

Master Periodic Table and Periodicity to gain a powerful tool for understanding all areas of Chemistry, especially Inorganic Chemistry, in school exams and competitive tests.
