Elements & Compounds
About Elements & Compounds
Master the 118 chemical elements of the periodic table and match everyday molecules to their chemical formulas
Elements & Compounds unites Periodic Table Master and Chemical Compounds into one chemistry trainer. In Elements mode, each round names one of the 118 elements from Hydrogen (1) to Oganesson (118) and you identify it by symbol, atomic number, or position on the interactive periodic table. In Compounds mode, you match everyday substances · water, table salt, baking soda, quartz, aspirin, caffeine · to their chemical formulas and molecular structures.
All 118 elements + everyday molecules. Switch between All (mixed), Elements (Periodic Table), and Compounds (Molecular Formulas) in the game settings menu.
Progressive difficulty. Easy rounds focus on the first 20 elements and household molecules (H₂O, NaCl, CO₂). Medium and hard rounds expand to all 118 elements, transition metals, lanthanides, and complex organic and mineral formulas.

FAQ
-
What modes are in Elements & Compounds?
Elements & Compounds combines Elements mode (identifying all 118 periodic table elements by symbol, atomic number, and group) and Compounds mode (matching common molecules and minerals to their chemical formulas), plus an All mode that alternates both. -
Why learn both elements and chemical compounds?
The periodic table gives you the building blocks of matter, and chemical formulas show how those atoms bond into the substances we encounter every day · from water (H₂O) and salt (NaCl) to glucose (C₆H₁₂O₆) and rust (Fe₂O₃). -
What is atomic number?
The atomic number is the number of protons in an atom's nucleus. It uniquely identifies each element · Hydrogen is 1, Helium is 2, and so on. -
How does difficulty work?
Difficulty 1-3 focuses on the first 20 elements and familiar household compounds. Difficulty 4-6 expands to the first 50 elements and laboratory acids/salts. Difficulty 7-10 includes all 118 elements and multi-element organic and mineral formulas. -
Can I play offline?
Yes. PlayMemorize is a Progressive Web App. -
Can MemPi help me study and practice this game?
Yes! Click MemPi in the header or on the game board to summon him. He observes the board, thinks out loud, and can demonstrate moves or guide you through tricky steps.
