ElementDrop is a calm, hands-on way to learn the periodic table. Pick a family of elements — alkali metals, halogens, noble gases, lanthanides, or the whole table — and a single element tile drifts gently down the screen. Drag it to its correct square on the full, always-visible periodic table and it locks into place with a fun fact; drop it in the wrong spot and it glides to where it belongs so you still learn its home. There is no timer, no lives, and no way to lose. Learn Mode glows the target square and quietly fades its help as you improve, while Test Mode leaves it all to memory. Once every element is placed, fact cards appear to match back to their elements. Built for ages 10 and up, it works with mouse or touch and needs no sign-up.
