About this app

Atomap is a periodic table of the elements for learning chemistry. It shows what each element builds. Tap an element to see its properties and the molecules it is part of, then follow a molecule to the everyday products that use it. It works the other way too: start from toothpaste and find the molecules and elements inside.

ELEMENTS
• All 118 elements with a clear, colour-coded table.
• Atomic mass, electron configuration, electronegativity, radius, melting and boiling points, density, ionization energy, electron affinity, oxidation states, discovery year and isotopes.
• Colour maps that show trends across the table, such as electronegativity or atomic radius.
• Pinch to zoom the table on phones.

MOLECULES AND PRODUCTS
• 67 molecules, from water and table salt to sodium fluoride and citric acid.
• Formula, molar mass, what it is used for and which elements it contains.
• GHS hazard pictograms and short safety notes where they apply.
• 40 everyday products in 8 groups. Find by product: what is in toothpaste, baking soda or bleach?

TOOLS
• Molar mass calculator with mass % for each element, hydrates included (CuSO4·5H2O).
• Solubility table: will this salt dissolve in water?
• Common ions with their charges.

DATA WITH SOURCES
• Values are checked against public references such as PubChem, NIST, IUPAC and IAEA, and each page lists its sources.
• Found a mistake? Tap "Found a mistake?" on any page to send it to us.
• Safety notes are for learning only. They are not a safety data sheet.

PHONES AND TABLETS
• Portrait and landscape on phones and tablets. On a large screen the table and the element sit side by side.
• Light, dark or system theme. In English, Korean, Japanese, German, French, Traditional Chinese, Spanish, Brazilian Portuguese, Italian, Hindi and Indonesian.
• Works offline. No account, no sign-up. Favorites and notes stay on your device, and you can export them to a file.

FREE, WITH AN OPTIONAL 24-HOUR PASS
Every element, molecule and product is free to read. A banner ad sits at the bottom of the screen, never full-screen.
Try every feature free for 7 days from the first launch. After that, reading stays free and the extra tools open with the optional pass below.
Watch a short optional ad to open the extra tools for 24 hours (up to 5 times a day; each one adds 24 hours): all colour maps, mixing two solutions to see if a precipitate forms, empirical formulas, calculation history and notes on favorites.
