All compounds are molecules but not all molecules are compounds. Molecular hydrogen (H 2), molecular oxygen (O 2) and molecular nitrogen (N 2) are not compounds because each is composed of a single element.
II. Compounds. A compound is a pure substance composed of two or more different atoms chemically bonded to one another. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two. The key distinction is that compounds break down whereas the SAME techniques do not cause an element to break down. The molecule is smallest subdivision of a compound that still retains the properties of that compound. The parallel definition (to the element one above) for the molecule is: the smallest part of a compound that can enter into a chemical combination
