2D PERIODIC TABLE
A grid layout by group and period. Categories like alkali metals, halogens and transition metals are color-coded, so you can see an element's classification at a glance. Pinch to zoom into crowded blocks of elements for a closer look.

ELEMENT DETAILS
Tap an element to see its electron configuration through an intuitive rotating shell animation. Dig deeper with atomic number, mass, melting and boiling points, density, electronegativity, year of discovery, real-world photos with usage examples (sourced and licensed), a list of isotopes, molecular structures of representative compounds (water, carbon dioxide, ozone and more), and electron configuration changes for common ions.
