To determine which statement is true regarding the three chemical structures (X, Y, and Z), we would need to analyze the characteristics of each model.
- Atom: Typically represented by a single sphere or a small structure, often indicating an element.
- Molecule: Represents a group of atoms bonded together (often depicted with several spheres connected).
- Extended Structure: Often indicates a repeating unit or a large structure that extends in multiple directions, such as a crystal lattice or polymer.
Based on general conventions:
- If Model X looks like a simple sphere or atom, it would likely represent an atom.
- If Model Y appears to be interconnected and more complex (like a larger grouping or consistent pattern), it could represent an extended structure.
- If Model Z is a simpler structure but more complex than a single atom (but not extensive like Y), it would represent a molecule.
Without seeing the actual models, we cannot definitively conclude which statement is correct. However, based on typical descriptions:
- If we assume X is an atom, Y is a molecule, and Z is an extended structure, then one possible option could be D: "X represents an atom, Y represents a molecule, and Z represents an extended structure."
Please refer to the details of the models for accurate matching against these attributes to confirm or revise this interpretation.
