O_2
D
Fe
Verified step by step guidance1
Step 1: Understand the definition of a molecule. A molecule is a group of two or more atoms chemically bonded together, typically involving covalent bonds between nonmetal atoms.
Step 2: Analyze each option to determine if it fits the definition of a molecule. For example, Na^+ and Cl^- are ions, not molecules, because they are single atoms with a charge.
Step 3: Consider O_2, which consists of two oxygen atoms bonded together covalently, making it a diatomic molecule.
Step 4: Fe is a single atom of a metal element and does not form a molecule by itself; it is an atom or part of a metallic lattice.
Step 5: Conclude that among the given options, only O_2 qualifies as a molecule because it is composed of two atoms bonded covalently.
