To accurately determine which statement best describes the molecule based on the given options, we need to identify the nature of the molecule.
- If the molecule is made up of more than one type of atom, it is likely a compound.
- If it is composed of separate substances mixed together without chemical bonding, it's a mixture.
- An atom is the smallest unit of an element and cannot be composed of different elements.
- An element consists of only one type of atom.
Given the options presented, the most appropriate one would be:
a compound composed of oxygen and carbon atoms.
This suggests that the molecule discussed is a compound, possibly carbon dioxide (CO2) or carbon monoxide (CO), both of which are common in the atmosphere and consist of carbon and oxygen atoms.
