Learn all 118 elements — symbol to name, name to symbol, or number to name — with multiple choice, instant feedback and a searchable reference table. The whole periodic table is embedded; nothing leaves your device.
Learn the pattern: elements sit in the table in order of atomic number — the number of protons. Symbols often come from Latin names: Fe (iron), Ag (silver), Au (gold), Pb (lead), Hg (mercury), Na (sodium), K (potassium).
