Element Quest - Periodic Table

Element Quest treats the periodic table's 118 elements as a map to explore, not a chart to memorize.

■ Interactive periodic table
Browse a color-coded table with 10 categories (alkali metals, transition metals, halogens, noble gases, and more). Tap any element to open a detail card with its symbol, atomic number, atomic weight, category, room-temperature state, discovery year, and a real-world use case.

■ 3 quiz modes
Choose from symbol-to-name, name-to-symbol, or category-matching quizzes, each with 4-choice questions. Pick a range - elements 1-20, 1-56, or all 118 - to set your difficulty.

■ Auto-building wrong-answer notebook
Elements you miss in a quiz are automatically added to your wrong-answer notebook, which you can revisit for focused practice. Getting an element right twice in a row removes it from the list.

■ Progress statistics
Track mastery gauges by category and group, plus a "N of 118 discovered" counter to see your overall progress at a glance.

■ Fully offline, built-in data
All 118 elements are bundled with the app, so you can study anywhere without an internet connection.

■ Korean/English support
Switch between Korean and English anytime from Settings.

Whether you're prepping for a chemistry exam or just curious about the elements, explore the periodic table with Element Quest.
