Chemistry Crossword Puzzles

Chemistry crossword puzzles make the periodic table feel less like homework and more like a puzzle, because it is one. The word lists cover elements and their symbols, the parts of the atom, states of matter, lab equipment, and the vocabulary every chemistry test expects: catalyst, solution, ion, and friends. Solving a grid turns out to be a surprisingly effective way to review, since every crossing double-checks your spelling of POTASSIUM.

Each puzzle is free to print, with the answer key on its own page. The easy 9x9 grids introduce friendly words like acid, base, and beaker; the 11x11 medium puzzles dig into electron shells, bonding types, and element names for middle and high school review. Teachers hand them out before unit tests, use them for early-finisher folders, and stash them in sub plans; students discover that study time goes faster with a pencil and a grid. Print on letter or A4 paper and react accordingly. For more science-adjacent fun, try our geography and animal crosswords in the full printable collection.
