In class we are learning about atoms. An atoms is broken up into protons, neutrons and electrons. Atoms have a nucleus made of the neutrons and protons. The nucleus is really hard to brake. Around the nucleus are the electrons, they orbit around the nucleus. An atom is tiny the amount of atoms in a grapefruit is equal to the amount of blueberries that fill the world. Then if you make one blueberry the size of a NFL football stadium only then will you see the nucleus. Atoms are everywhere so it is important to understand them.
