Answer:
A. "All molecules are compounds, but not all compounds are molecules"
Explanation:
An example of a compound-molecule is oxygen. The elemenal is O, because the periodic table isn't describing molecules, it's describing atoms. The molecule is O2 because it takes 2 O atoms to make a molecule of oxygen.
The primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom'.
Explanation:
- A molecule is a group of atoms of the same or different types of atoms bound to each other.
- Molecules are the smallest unit of a substance that possesses the characteristic of the substance.
- A compound is a substance in which two or more different types of atoms are bound to each other.
- In compounds, atoms of different elements are in a fixed proportion.
So, from this, we can conclude that the primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom'.
