What is an Atom? The Tiny Building Block of Everything! Have you ever wondered what you, your phone, the ocean, and the air you breathe are made of? If you zoom in close enough—past microscopic cells and molecules—you will find the ultimate building block of the universe: the Atom . An atom is the smallest particle of an element that retains its chemical identity. Think of atoms like LEGO bricks. Just as you can build a house, a car, or a spaceship using different combinations of LEGO bricks, nature builds stars, trees, and humans using different combinations of atoms. 🏗️ The 3 Main Subatomic Particles Even though an atom is incredibly small, it is made up of three even smaller particles Protons: Located in the center (nucleus). They carry a positive electrical charge . Neutrons: Also in the nucleus. They carry no charge (they are neutral) and act as nuclear glue to keep the nucleus stable. Electrons: Tiny, super-fast particles orbiting the nucleus in energy levels or shells....
