The periodic table can be used to predict properties of elements, even those that are yet to be discovered. By studying it you get to understand some trends in a group of elements and how chemical reactions may occur. Below is a quiz to test you on Chapter 5 which covered the organization, properties, and discovery of the periodic table.
