20. What is an atom composed of?
- Protons, neutrons, and electrons

21. Ionic compounds: give examples and explain
- Ionic compounds are substances that are composed of positive and negative ions. They have no net electrical charge; they are neutral because the positive and negative electrical charges offset each other. 
Example: Table salt (sodium chloride).
