Atomic - Periodic Table

Atomic is a periodic table for schoolwork and for curiosity. Tap an element and you get as much or as little as you need: atomic weight and the basics for a quick check, or electron configuration, ionisation energy and isotope half-lives when the homework gets serious.

The main table can swap which data it shows with one tap, colouring the whole grid by a property so the trends jump out. There are separate tables for electronegativity, solubility and the electrochemical series, plus a built-in dictionary for the terms nobody explains.

Most of it works without a connection, though element images are fetched online unless you turn offline mode on. There are no ads, but a paid PRO upgrade unlocks extra data, extra tables and more of the study features, and syncing your notes and progress between devices means signing in with a Google account. The app reports usage data to Google's Firebase.
