Answer:
A. Lithium and Bromine (LiBr)
Explanation:
Ionic bonds are chemical compounds formed between a metal and nonmetal. Lithium is a metal and Bromine is a nonmetal, therefore they would combine to produce an ionic bond.
- Oxygen and Hydrogen are both nonmetals, therefore they cannot produce an ionic bond when combined.
- Carbon and Oxygen are both nonmetals, therefore they cannot produce an ionic bond when combined.
- Nitrogen and Fluorine are both nonmetals, therefore they cannot produce an ionic bond when combined.
