When only like atoms combine, they form elements, so technically, elements can be composed of molecules. An atom can be considered as the smallest amount of an element. It is the simplest unit of matter, and has a closely packed nucleus in its center. Surrounding the nucleus is a cloud of electrons, which are the negatively-charged particles of an atom.
