Chemistry Quiz

Element Quiz You're shown an atomic number, name, or symbol and asked to identify one of the others. Choose elements 1–20 (easy), 1–20 plus key metals (hard), or all 118 elements (hell).

Compound Naming You're shown a chemical formula or compound name and must provide the other. Choose ionic or covalent compounds and pick an easy/hard/hell pool.

Infinite Keep playing as long as you like, with no time or question limit.

Timed Answer as many as you can in 1, 3, or 5 minutes.

Survival Complete all questions before your hearts run out. Each wrong answer costs a heart; you also have a per-question timer. Finishing a full survival run earns a trophy.

Type English element or compound names, symbols or formulas as requested, then press Enter or Check. Changing the interface language does not change accepted answers. Some compounds accept common alternate names (e.g. "ammonia" for NH₃). English names are case-insensitive; symbols and formulas require correct capitalisation.
