Periodic Table & Chemistry
Element Facts, Reactions, Quiz
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
All 118 elements in real depth — shell diagrams, named reactions, trend views and a quiz. Everything runs offline on your device, no accounts and no ads.
The periodic table you'll actually understand — all 118 elements, tap any cell and get the full story.
Most periodic table apps stop at a symbol and an atomic mass. PeriodicTab goes deeper: every element opens into atomic mass, electron configuration, a Bohr shell diagram, melting and boiling points, density, electronegativity, who discovered it, and what it is really used for. Then it goes past the table entirely — a library of named reactions, a bonding lab that shows two elements combining into a compound, periodic-trend views, and a quiz that makes it stick. Every element, equation and chart is built into the app, so it works in the exam hall, the lab, or on the bus with no signal.
WHAT YOU GET
- The complete table of 118 elements, color-coded by category — tap any cell for the full element page
- Deep element pages: atomic mass, electron configuration, Bohr shell diagram, melt and boil points, density, electronegativity, discovery and common uses
- A library of 16 classic named reactions with balanced equations and type filters, plus a bonding lab that builds NaCl, H2O, MgO and more from two elements
- Periodic-trend views for atomic radius and electronegativity, mapped straight onto a mini table
- Instant search by name, symbol or atomic number, with filters for category, group and state and sorting by number, name, mass or electronegativity
- A 10-question element quiz that scores your recall of symbols, names and categories
PERFECT FOR
- Students revising for a chemistry exam
- Teachers who need a clean reference on screen
- Lab and research workers who want fast element lookups
- Anyone simply curious about what the world is made of
WHY NOT JUST SEARCH THE WEB?
A web search gives you ten tabs and an argument. PeriodicTab gives you one calm, offline reference where every element, reaction and trend is one tap away — no ads, no pop-ups, no waiting on a connection.
PRIVACY
Everything is stored and calculated on your device. No accounts, no ads, no tracking — your favorites and quiz results never leave your phone.
FULL ACCESS
Full access to PeriodicTab is unlocked with Premium: the complete element library and detail pages, the reaction library and bonding lab, periodic-trend views, the element quiz, and unlimited favorites instead of the 3-item free limit. Choose the plan that fits — Weekly, Yearly, or a one-time Lifetime purchase. Payment is charged to your Apple ID at confirmation. Weekly and Yearly plans renew automatically unless auto-renew is turned off at least 24 hours before the current period ends; manage or cancel anytime in your App Store account settings. Lifetime is a single payment with no renewal.
Open the table and tap your first element.
