About the Periodic Table
What is the Periodic Table?
The periodic table is a tabular arrangement of chemical elements organized by atomic number, electron configuration, and recurring chemical properties. Elements are presented in order of increasing atomic number.

Element Properties
- Atomic Number: Number of protons in the nucleus
- Atomic Mass: Average mass of atoms (in atomic mass units)
