To determine which model represents the chemical formula \( \text{NO}_2 \) (nitrogen dioxide), we need to break down the components of the formula.
- N represents nitrogen.
- O represents oxygen, and since there are two \( O \) atoms in \( \text{NO}_2 \), we will have two representations of oxygen in the model.
The correct model should contain one nitrogen atom and two oxygen atoms. If you provide the options (A, B, C, D) as visual or descriptive representations of the molecular structure, we would be able to identify which model corresponds to nitrogen dioxide.
Please provide more details about the models or images associated with A, B, C, and D so that I can help you choose the correct one!
