Elementum
Chemistry, Made Simple
Free · Designed for iPad. Not verified for macOS.
Explore all 118 elements, meet a new one every day, and combine elements to see how they react, predicted right on your iPhone, even offline.
Elementum is a beautifully simple way to explore the periodic table.
Discover elements, understand their properties, and see how they come together, all through a clean, intuitive interface designed for clarity and focus.
Explore Elements
See all 118 elements in a full periodic table, or browse them block by block: s, p, d and f. Each block has its own colour, so you always know where an element belongs.
Element of the Day
Start each day with a new element. Elementum shows you what it is, why it matters, and exactly where it sits in the table.
Understand Every Element
Tap any element to see its atomic number, atomic mass, electron configuration, block, bonding type, phase, appearance, who discovered it, and a short description in plain language.
Combine Elements
Pick elements and compounds, set how many of each, and Elementum predicts the reaction: a balanced chemical equation and a one-line explanation of what happens. If two substances don't react, it tells you why. You can also build and save your own compounds.
Private and On Device
Reactions are predicted by a language model that runs entirely on your iPhone or iPad. Download it once and Combine works offline, and your experiments never leave your device.
Find Anything Fast
Search by name, symbol or atomic number and jump straight to the element you need.
Made for iPhone and iPad
On iPad, Elementum uses a sidebar layout, so you can browse the table and read about an element side by side.
Elementum was made by a student developer and is a Swift Student Challenge 2025 winner. It's built for students, teachers and anyone curious about the building blocks of everything around us.
Note: reaction predictions are generated by an on-device AI model and are meant for learning. Always check important results against your textbook or teacher.
