A chemical element bonded to an identical chemical element is not a chemical compound since only one element, not two different elements, is involved. Examples are the diatomic molecule hydrogen (H 2) and the polyatomic molecule sulfur (S 8).
Examples of Inorganic Compounds: 1  1. H2O - Water is a simple inorganic compound, even though it contains hydrogen, a key atom (along with carbon) in many organic compounds. 2  3. CO2 - Carbon dioxide, despite the presence of a carbon atom in the formula, is classified as an inorganic compound.
