The Periodic Table of Elements is a systematic arrangement of all known chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties. Each element is represented by a unique symbol, typically one or two letters, and is placed in a specific location based on its characteristics. The table is divided into rows called periods and columns known as groups, which help to categorize elements with similar properties. The table includes essential information such as the atomic mass and the state of matter at room temperature for each element. It serves as a valuable tool for scientists and students, providing insights into the relationships between different elements and their behavior in chemical reactions.
