This reference table lists the standard Greek prefixes used to indicate the number of atoms in binary molecular compounds.

- The image displays a table listing prefixes used for naming binary molecular compounds.
- These prefixes indicate the number of atoms of each element present in the compound.
- The prefix "mono-" is used for one atom, "di-" for two, "tri-" for three, and so on up to "deca-" for ten atoms.
- When naming a binary molecular compound, the first element is named using its elemental name, and the second element is named with an "-ide" suffix.
- Prefixes are added before each element's name to denote the number of atoms, except "mono-" is typically omitted for the first element.
- For example, CO₂ is named carbon dioxide (one carbon, two oxygen atoms), and N₂O₅ is named dinitrogen pentoxide (two nitrogen, five oxygen atoms).
