Atom

Atoms are tiny pieces of matter that make up everything around us. It’s like a puzzle – if you put all the atoms together, you get the things we can see, like a chair, a tree, or a person. All atoms are made up of even smaller parts called protons, neutrons, and electrons. Protons and neutrons are in the middle, and they stick together. The electrons are in a cloud around the middle and they move really fast.
