  2. Carbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide

    Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...

  3. Cobalt - Wikipedia

    en.wikipedia.org/wiki/Cobalt

    Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.

    Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...

  5. Monoxide - Wikipedia

    A model of the carbon monoxide molecule. A monoxide is any oxide containing only one atom of oxygen. A well known monoxide is carbon monoxide; see carbon monoxide poisoning. The prefix mono (Greek for "one") is used in chemical nomenclature. [1] In proper nomenclature, the prefix is not always used in compounds with one oxygen atom. [2]

  8. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [1]

  9. Dicarbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Dicarbon_monoxide

    Dicarbon monoxide is a product of the photolysis of carbon suboxide: [2] [3]. C 3 O 2 → CO + C 2 O. It is stable enough to observe reactions with NO and NO 2. [4]Called ketenylidene in organometallic chemistry, it is a ligand observed in metal carbonyl clusters, e.g. [OC 2 Co 3 (CO) 9] +.
