Explanation:

Step1: Classify ionic/covalent bonds

Ionic bonds form between metals (groups 1-2, transition metals) and nonmetals; covalent bonds form between nonmetals (including same-element molecules). For ionic compounds with polyatomic ions, the overall compound is ionic.

Step2: Assign bond type to each compound

1. $\text{BaO}$: Ba (metal) + O (nonmetal) → Ionic
2. $\text{Na}_2\text{O}$: Na (metal) + O (nonmetal) → Ionic
3. $\text{NI}_3$: N (nonmetal) + I (nonmetal) → Covalent
4. $\text{CBr}_4$: C (nonmetal) + Br (nonmetal) → Covalent
5. $\text{CaCl}_2$: Ca (metal) + Cl (nonmetal) → Ionic
6. $\text{H}_2\text{O}$: H (nonmetal) + O (nonmetal) → Covalent
7. $\text{Al}_2\text{O}_3$: Al (metal) + O (nonmetal) → Ionic
8. $\text{Mg}_3\text{P}_2$: Mg (metal) + P (nonmetal) → Ionic
9. $\text{O}_2$: Same nonmetal atoms → Covalent
10. $\text{NaCl}$: Na (metal) + Cl (nonmetal) → Ionic
11. $\text{SO}_2$: S (nonmetal) + O (nonmetal) → Covalent
12. $\text{FeCl}_2$: Fe (metal) + Cl (nonmetal) → Ionic
13. $\text{H}_2$: Same nonmetal atoms → Covalent
14. $\text{PI}_3$: P (nonmetal) + I (nonmetal) → Covalent
15. $\text{BaSO}_4$: Ba (metal) + $\text{SO}_4^{2-}$ (polyatomic ion) → Ionic
16. $\text{KI}$: K (metal) + I (nonmetal) → Ionic
17. $\text{CH}_4$: C (nonmetal) + H (nonmetal) → Covalent
18. $\text{LiBr}$: Li (metal) + Br (nonmetal) → Ionic
