Chapter 5 - Periodic Table
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.
