Major Groups

Major groups are broad categories used to organize chemicals based on their shared features or functions. For example, in chemistry, elements are grouped into metals, nonmetals, and metalloids. In medicine, drugs are classified into categories like antibiotics or antidepressants. These groupings help scientists and professionals understand relationships, predict behavior, and communicate more effectively. Think of major groups as the main chapters in a book, where each chapter covers specific related topics, making complex information easier to navigate and study.
