All 118, one card at a time.
A pocket-sized periodic table card that shows one element at a time — symbol, atomic number, atomic mass, category pill, and a one-line memorable use. Press refresh to spin to a different random element. Tick the Known checkbox to mark elements you've memorized; refresh skips them until you've learned all 118.
All 118 elements baked in with EN + AR names and category color-coding (alkali, transition, halogen, noble gas, lanthanide, actinide, and the rest). Light + dark, three sizes, and a per-deck ns namespace so two embeds can hold separate progress.
