The periodic table is a fascinating tool that organizes elements based on their atomic structure and properties. Understanding periodic trends is essential for grasping the behavior of elements in chemical reactions. This quiz will challenge your knowledge of these trends and help you see patterns that govern the elements. Good luck and enjoy the challenge!
