Here's why:
* Compounds are formed by the chemical combination of two or more different elements in a fixed ratio.
* Molecules are the smallest unit of a compound that can exist independently.
* A molecule of a compound contains all the atoms of the different elements that make up the compound in the correct ratio.
* Breaking down a molecule further would result in individual atoms, which would no longer have the properties of the original compound.
Example:
* Water (H₂O) is a compound.
* A single molecule of water (H₂O) contains two hydrogen atoms and one oxygen atom.
* This molecule retains the properties of water, such as being a liquid at room temperature and being a good solvent.
