Periodic Table - Chemistry

Offline periodic table with 118 elements, Bohr diagrams, study sets & notes.

Periodic Table Navigator is an offline chemistry reference that puts all 118 chemical elements in your pocket. Tap any element for instant details, compare elements side by side, and build your own study sets - all without internet.

Explore the full interactive periodic table with a grid you can pan, zoom and fit to screen, or switch to a searchable list filtered by category. Every element page shows atomic number, atomic mass, electron configuration, group and period, category, state at STP, density, melting and boiling points, electronegativity, ionization energy, atomic radius, oxidation states, and discovery credits. A visual Bohr diagram shows the atomic structure and outer electrons at a glance.

For revision, create custom study sets, add elements to favourites, and write your own notes with mnemonics, exam facts, and reactions to remember. A recent-views list helps you pick up where you left off.
