Verified step by step guidance1
Step 1: Understand the difference between ionic and covalent compounds. Ionic compounds typically form between metals and nonmetals, involving the transfer of electrons, while covalent (molecular) compounds form between nonmetals, involving the sharing of electrons.
Step 2: Identify the elements in each compound and classify them as metals or nonmetals. For example, Ba (Barium), Fe (Iron), and Zn (Zinc) are metals, while O (Oxygen) is a nonmetal.
Step 3: Analyze each compound: BaO consists of a metal (Ba) and a nonmetal (O), Fe2O3 consists of a metal (Fe) and a nonmetal (O), and ZnO consists of a metal (Zn) and a nonmetal (O).
Step 4: Since all these compounds are formed between metals and nonmetals, they are ionic compounds rather than covalent (molecular) compounds.
Step 5: Conclude that none of the given compounds are covalent (molecular) compounds, which matches the correct answer: None of the above.
