📚 About the Periodic Table
The periodic table organizes all known chemical elements by atomic number, electron configuration, and recurring chemical properties. Created by Dmitri Mendeleev in 1869.
🔬 Periods & Groups
Periods (rows) show elements with the same number of electron shells. Groups (columns) show elements with similar chemical properties.
⚛️ Element Categories
Elements are classified into metals, nonmetals, and metalloids based on their physical and chemical properties. Each category has distinct characteristics.
