Introduction to the periodic table: quiz. The periodic table displays all known elements, their atomic number and chemical properties. The periodic table is divided into eight groups, each representing common properties elements has. How many periodic tables are there? By taking this exciting quiz, you will get to test out just how much you know about the table and how to interpret the information it has to offer. All the best!
