Explore all 118 elements with interactive data, periodic trend visualizations, and electron configuration tools.
Explore the TableInvestigate atomic mass, melting point, boiling point, density, electronegativity, ionization energy, and electron affinity for every element.
Visualize how atomic radius, ionization energy, electronegativity, and metallic character change across periods and down groups.
Build electron configurations using the Aufbau principle, Hund's rule, and the Pauli exclusion principle with interactive orbital diagrams.
Click any element for detailed properties, uses, discovery history, and isotope information.
Color-coded heat maps and graphs showing periodic trends across the entire table.
Fill electron orbitals step by step following quantum mechanical rules with visual feedback.
Predict reactivity and common compounds based on electron configuration and electronegativity.
The trend visualizer's heat maps made periodic trends instantly obvious. No more memorizing rules.Mrs. Powell, Chemistry
Building electron configurations interactively with the orbital diagrams was so much better than worksheets.Liam K., Grade 10
