Quick comprehension check
“If you were to build a model of oxygen gas (O₂), what would you use to represent the oxygen atoms, and how would you connect them? Imagine you are building a model of a simple table salt crystal (NaCl). How would you arrange the sodium (Na) and chlorine (Cl) atoms to represent its extended structure? If you were to build a model of carbon dioxide (CO₂), what would you use to represent the carbon and oxygen atoms, and how would they be arranged in your model?”
