A molecular illustration of carbon monoxide, a molecule consisting of one carbon and one oxygen atom connected by two covalent and one dative covalent bond. Carbon monoxide in high concentrations is toxic to humans, and is produced when carbon compounds are oxidated and are unable to bond with additional oxygen molecules to form carbon dioxide (CO2). Machines using internal combustion engines can produce carbon monoxide when there is insufficient oxygen in the surrounding environment, as can malfunctioning household devices that burn fuel, such as furnaces, gas heaters or water heaters. Atoms are coloured dark grey (carbon) and red (oxygen).
