As common as dirt. Because dirt is made of atoms. Of course everything material is made of atoms.
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.

Propene, or propylene, is a common type of alkene composed of three bonded carbon atoms.
The common name for a compound made of iron and oxygen atoms is iron oxide.
All hydrogen atoms have one proton and one electron.
The most common fullerene, C60, has 60 carbon atoms
The common characteristic shared by all organic substances is that they contain carbon atoms bonded to hydrogen atoms.
Sugar is a common example of a compound with carbon atoms bonded to hydrogen and oxygen atoms. Compounds made from carbon, oxygen and hydrogen often fall under the category of carbohydrates, which are common to almost every living thing (including you!). Common table sugar is sucrose, and has the chemical formula C12H22O11. That's a common carb that you probably encounter daily.
