In molecular models, the representation of atoms and bonds can vary based on the specific visualization system being used. Generally, however:
- Black balls often represent carbon atoms.
- In some models, white balls might represent hydrogen atoms.
- Red balls are commonly used to represent oxygen atoms.
- Bonds between atoms are usually depicted by rods or sticks connecting the balls.
If you're looking at a specific molecular model, it might be helpful to refer to a key or legend that often accompanies the model, which explains what each colored ball represents.
