Title

How Small Is An Atom?

Reading Text

Have you ever wondered what things are made of? Everything in the universe is made of tiny particles called atoms. Atoms are very, very small. A single human hair is much wider than an atom. In fact, one hair is as thick as 500,000 atoms! An atom has a center called the core. Inside the core, there are protons and neutrons. There are also electrons. The electrons move around the core very fast. Here is a surprise: Atoms are mostly empty space. If we remove the empty space, all the people in the world could fit inside a teaspoon. It is hard to imagine, but it is true!
