In the following game of concentration, first click on the appropriate category to choose whether you want to match the name of a chemical element with its chemical symbol or with its atomic number.

Clicking on a square reveals either the name of a chemical element or the chemical symbol of an element (or the atomic number of an element). Click on a second square to try to find the name or symbol (or atomic number) that matches. Every time you succeed in finding a matched pair, the pair is blanked out. Keep trying until you have found all 12 pairs. Click on the grid to play again.
