Group

Real World Example

Imagine trying to organize your kitchen pantry, where you group all similar types of canned foods together on the same shelf. This is similar to the periodic table, where elements in the same vertical column, or group, share similar chemical properties. Just as each shelf is dedicated to a specific type of canned food—like all soups or all beans—each column in the periodic table contains elements that behave similarly in chemical reactions, making it easier to predict their behavior just like you can easily find what you're looking for in your pantry.
