Atoms are the tiny building blocks that make up everything in the universe. They are the smallest unit of matter that still retains the properties of a specific chemical element.

• Atoms are like super small LEGO® bricks used to build everything around you—from a chair to a tree, even yourself!

Examples of atoms:

• HydrogenHydrogen is the lightest and most abundant chemical element in the universe. It’s a colorless, odorless gas that’s essential for life. Think of it like this: • Hydrogen is the basic building block of the universe. • It’s a part… Read More atom (the simplest atom)
• CarbonCarbon is a chemical element, one of the fundamental building blocks that make up everything around us. It’s a versatile atom that can form bonds with other elements, including itself, creating an astonishing variety of molecules. Think of carbon as… Read More atom (found in all living things)
• Oxygen atom (part of the air we breathe)
• Gold atom (creates the shiny metal)
