Practise the periodic table by matching chemical elements, symbols and atomic numbers. Start with elements 1–20, choose another range or try all 118. Exercises include symbol-to-element and atomic-number questions in both directions. Element names in the exercises currently remain English, even when you choose another interface language.
Choose a question type, an element range and 60 or 120 seconds. Begin with a small range to learn the connections, then expand it. Compare the symbol and atomic number carefully before selecting an answer.
Which element has the symbol Na?
Sodium, with atomic number 11. The symbol Na comes from the Latin name natrium; it does not follow the English spelling.
