## What is Periodic Table?

Periodic Table - Elementum Pro is a fully offline chemistry reference and self-testing trainer built for students facing a real exam. Every app in this category shows you the table; this one quizzes you back, turning the periodic table into an answer sheet so you practice active recall instead of passive reading.

Explore all 118 elements in the classic layout, open detailed element pages with electron configuration, oxidation states, electronegativity, atomic radius and more, browse isotope data, and read twelve printed-style reference tables. Type any formula, including nested parentheses like Ca(NO3)2, into the molar mass calculator for an instant per-element breakdown. Every value carries a named published source and honours your own rounding convention, and nothing is generated by AI.

Included in free tier: the full interactive periodic table, element detail pages, isotope data, twelve reference tables, the molar mass calculator with configurable rounding, personal notes and favourites, and a daily drill to sample the training engine. Everything works with no account, no ads, and no internet connection.

Included in premium tier: Elementum Pro unlocks all six drill modes, covering symbol and name recall, blank-grid placement, periodic-trend ordering, oxidation states and Lewis dot structures, plus a spaced-repetition review queue that resurfaces what you miss, unlimited drill scope, and full progress stats with a daily study streak.

Study the way your exam tests you, trust every number you see, and do it all offline. Download Periodic Table - Elementum Pro and let the table quiz you back.
