  1. Atoms are very tiny particles that make up everything around us. (Page 1)
  2. Atoms are so small that we can’t see them with our eyes. (Page 1)
  3. Atoms are made up of even smaller particles called protons, neutrons, and electrons. (Page 2)
  4. Protons have a positive charge, while electrons have a negative charge. (Page 2)
  5. Neutrons have no charge at all. (Page 2)
  6. Atoms can combine with other atoms to form molecules. (Page 3)
  7. Different elements have different numbers of protons in their atoms. (Page 4)
  8. The number of protons in an atom determines what element it is. (Page 4)
  9. Atoms can gain or lose electrons to become ions. (Page 5)
  10. Understanding atoms is important for understanding how the world works. (Page 6)
