How to Play

The Interactive Periodic Table offers four exploration modes. In Learn mode, the full table is displayed with filtering by category (alkali metals, noble gases, transition metals and more) and search by name or symbol. Tapping any element opens its detail panel showing atomic number, mass, physical state, period, group, and a scientific curiosity. In Challenge mode, multiple-choice questions test your knowledge: identifying elements by name, symbol, atomic number, category, or physical state. A progressive hint system helps when you get it wrong — 2 mistakes reveal the period, 3 the group, 4 the position in the table. There are 4 difficulty levels that increase the number of questions and reduce available hints. In Time Attack mode, a timed progress bar adds pressure to every question. In Daily Mission mode, 5 themed missions offer bonus XP for completing them every day. An XP system with 8 achievements tracks your journey.

Tips & Strategy

1. 1Start with Learn mode and explore categories one by one — filtering by "alkali metals" or "noble gases" lets you learn each family's patterns before being tested.
2. 2One or two-letter symbols almost always come from the Latin or German name: Fe = Ferrum (iron), Au = Aurum (gold), W = Wolfram (tungsten) — learning these origins helps with memorization.
3. 3In Challenges, use hints strategically: period and group together locate the element on the table precisely — combine both to deduce the element even without knowing the name.
4. 4Watch out for physical state exceptions: mercury (Hg) is the only metal liquid at room temperature; bromine (Br) is the only liquid non-metal. These facts appear frequently in questions.
5. 5Complete the Daily Missions every day — beyond bonus XP, they present elements from varied categories, accelerating your learning of the complete table.
