diòxid

diòxid is a term used in chemistry to denote a compound containing two oxygen atoms. It is often encountered as a prefix in the names of certain oxides. For example, carbon dioxide (CO2) is a well-known diòxid of carbon. In this case, the "di" prefix clearly indicates the presence of two oxygen atoms bonded to a central carbon atom. Similarly, sulfur dioxide (SO2) is a diòxid of sulfur, also featuring two oxygen atoms. The term diòxid itself is not a specific chemical substance but rather a descriptive component of a chemical name, signifying a particular stoichiometric ratio of oxygen within a compound. Understanding the "diòxid" part of a chemical name helps in predicting the molecular formula and understanding the basic composition of the substance. Many important substances in industry and the environment are classified as diòxids, playing various roles in chemical processes and natural cycles.
