👉 Uncompoundable is a type of compound that does not contain any other substances. In chemistry, it refers to compounds where all atoms or ions are identical in their chemical properties and composition. Examples of uncompoundable compounds include water (H2O), ammonia (NH3), carbon dioxide (CO2), and sodium chloride (NaCl). These compounds do not contain any elements or isotopes other than hydrogen and oxygen, which are the basic building blocks of life.
