Overview
The periodic table is a chart that organizes all known chemical elements based on their properties. Each element has a unique atomic number and is placed in a specific position according to its electron configuration. Understanding the periodic table helps students learn about element relationships, trends, and how they interact in chemical reactions. This foundational knowledge is essential for further studies in chemistry and related sciences.
