Here are the matches for the element pairs and their most likely bond categories:
- Bromine and Aluminum - Ionic Bond (bromine is a nonmetal and aluminum is a metal)
- Nitrogen and Sodium - Ionic Bond (sodium is a metal and nitrogen is a nonmetal)
- Oxygen and Hydrogen - Covalent Bond (both are nonmetals and share electrons)
- Copper and Copper - Metallic Bond (between two metals)
- Fluorine and Sulfur - Covalent Bond (both are nonmetals and share electrons)
So the final matches are:
- Bromine and Aluminum: Ionic Bond
- Nitrogen and Sodium: Ionic Bond
- Oxygen and Hydrogen: Covalent Bond
- Copper and Copper: Metallic Bond
- Fluorine and Sulfur: Covalent Bond
