Elemora: Periodic Table Quiz

Elemora is a periodic table you can open anywhere and actually learn from. Every element and every detail is built into the app, so it works with no internet connection, and nothing is locked behind a subscription. TAP ANY ELEMENT • All 118 elements on one screen, sized to fit your phone in portrait. Pinch to zoom, tap to open. • Each element shows atomic number, standard atomic weight, group, period, block, category, electron configuration, state at room temperature, melting and boiling point, density, electronegativity and the year it was discovered. • An electron shell diagram for every element, plus a short line on what it is used for in real life. • Swipe left or right to move to the previous or next element. SEE THE PATTERNS • Color-coded families: alkali metals, alkaline earth metals, transition metals, metalloids, halogens, noble gases, lanthanides, actinides and more. Tap a family to highlight it. • Trend views turn the table into a heat map of electronegativity, atomic radius, melting point or atomic weight. • Sorted lists by any property, with units. MEMORIZE WITH QUIZZES • Five quiz modes: symbol to name, name to symbol, atomic number, element category, and find it on the table. • Choose a range that matches your class: elements 1–20, 1–36, 1–54 or all 118. • 10-question rounds with a clear result screen, a mistake list you can practice again, and a mastery mark when you get an element right three times in a row. • A daily goal and streak to keep you going, from the first chemistry class to last-minute exam review. EVERY DAY • Element of the day on the home screen, in a home screen widget and in an optional morning reminder. • Memory tips for learning the order of the elements. • Light and dark theme, temperature in °C, K or °F. Data follows IUPAC standard atomic weights and public NIST reference data. Category boundaries that textbooks disagree on, such as some metalloids, are labeled as the common classification. No account, no sign-up. Your favorites, quiz results and streak stay on your phone.
