About this quiz
Slots run in atomic-number order within each period. Names match instantly. A symbol only counts when you press Enter, otherwise typing S would fill sulfur before you got to sodium. Aluminum, sulphur, cesium, wolfram and the Latin names all land.
Matching happens on every keystroke, so there is nothing to press. Each answer also takes its common alternates. Give up at any time and the ones you missed appear in outline. Your best score is kept in this browser only.
Nothing you type is sent anywhere. The only thing this page records is that the quiz finished, and the score.
