Here's a breakdown:
* Molecular compounds are formed when two or more nonmetal atoms share electrons to form covalent bonds.
* Molecules are the smallest unit of a molecular compound that retains the chemical properties of that compound. They consist of two or more atoms held together by covalent bonds.
For example, water (H₂O) is a molecular compound. A single water molecule is the smallest unit of water that has the properties of water. It consists of two hydrogen atoms and one oxygen atom held together by covalent bonds.
