Oxygen is an element. This means that it is composed of only one kind of atom, and it takes two atoms of oxygen to make one molecule of oxygen.

A compound is composed of more than one kind of element. A simple example is carbon dioxide which is composed of one atom of carbon and two atoms of oxygen.

A mixture is composed of more than one kind of compound.
