Free interactive periodic table with all 118 chemical elements. Explore atomic numbers, symbols, weights, electron configurations, and element properties. Click any element for detailed information.
The periodic table is a tabular arrangement of chemical elements, organized by atomic number, electron configuration, and recurring chemical properties. This interactive version lets you explore all 118 confirmed elements with detailed properties, phase information, and historical discovery data. All data is displayed instantly in your browser — no server requests needed.
As of 2026, the periodic table contains 118 confirmed chemical elements, ranging from hydrogen (atomic number 1) to oganesson (atomic number 118). Elements 1–94 occur naturally, while elements 95–118 have been synthesized in laboratories.
Each color represents a different category of elements: alkali metals (red), alkaline earth metals (orange), transition metals (yellow), post-transition metals (green), metalloids (teal), nonmetals (blue), halogens (purple), noble gases (pink), lanthanides (brown), and actinides (dark brown).

Absolutely. This periodic table is designed for students, teachers, chemists, and anyone interested in exploring the elements. Feel free to use it for homework, research, or classroom presentations.
All data is sourced from IUPAC (International Union of Pure and Applied Chemistry) and NIST (National Institute of Standards and Technology) standards. Atomic masses use the standard atomic weights, and properties are regularly verified against authoritative chemistry references.
