Elements, Atoms, and Molecules. For a more advanced list of resources on atoms, elements and compounds. Elements are substances that cannot be separated into simpler substances. Salt is made up of the elements sodium and chloride. Water is made up of the elements hydrogen and oxygen. The smallest particles of matter are called atoms.
