key 
white atoms:  atom of one element 
black atoms: atom of a different element

GPT-4o mini · Answer

To illustrate a mixture of oxygen (O2) and nitrogen (N2) gases using the provided key, you would represent the gases with distinct atom colors.

Following the key:

Use white atoms to represent the oxygen (O2) molecules. Since oxygen is diatomic, you would depict two white atoms bonded together (O=O).
Use black atoms to represent the nitrogen (N2) molecules. Similarly, nitrogen is diatomic, so you'd show two black atoms bonded together (N≡N).

In the diagram you choose, you should see clusters of white atoms (representing O2) and clusters of black atoms (representing N2) without any specific bonding between different atoms, indicating that they are a mixture and not a compound.

The correct diagram should depict multiple instances of O2 and N2 molecules simply mixed together, without any interaction or bonding between the different colors.
