Elementii

The map of matter

118 kinds of atoms.
Everything is made of them.

Every confirmed element — and the table isn't frozen: rearrange it, light up a family, or ask what's solid, liquid, or gas in the room you're sitting in. Tap any tile to meet the atom.

The classic layout — columns hold family resemblances, rows fill up electron by electron.
