  2. Chlorine oxide - Wikipedia

    en.wikipedia.org/wiki/Chlorine_oxide

    Oxygen fluoride(s), bromine oxide(s), iodine oxide(s) – analogous oxygen halide and halogen oxides Sulfur fluoride (s), sulfur chloride (s), sulfur bromide (s), sulfur iodide (s) – analogous sulfur halides, some of which are valence isoelectronic with chlorine oxides.

  3. Chlorine monoxide - Wikipedia

    en.wikipedia.org/wiki/Chlorine_monoxide

    Chlorine monoxide is a chemical radical with the chemical formula ClO •. It plays an important role in the process of ozone depletion. In the stratosphere, chlorine atoms react with ozone molecules to form chlorine monoxide and oxygen. Cl • + O 3 → ClO • + O 2. This reaction causes the depletion of the ozone layer. [1]

  4. Chlorine dioxide - Wikipedia

    en.wikipedia.org/wiki/Chlorine_dioxide

    Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C. It is usually handled as an aqueous solution.

  5. Hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Hypochlorite

    In chemistry, hypochlorite, or chloroxide is an anion with the chemical formula ClO −. It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). [1] The Cl-O distance in ClO − is 1.69 Å ...

  6. Dichlorine monoxide - Wikipedia

    en.wikipedia.org/wiki/Dichlorine_monoxide

    Dichlorine monoxide is an inorganic compound with the molecular formula Cl 2 O. It was first synthesised in 1834 by Antoine Jérôme Balard, [2] who along with Gay-Lussac also determined its composition. In older literature it is often referred to as chlorine monoxide, [3] which can be a source of confusion as that name now refers to the ClO ...

  7. Oxygen - Wikipedia

    en.wikipedia.org/wiki/Oxygen

    Oxygen is the third most abundant chemical element in the universe, after hydrogen and helium. [68] About 0.9% of the Sun's mass is oxygen. [19] Oxygen constitutes 49.2% of the Earth's crust by mass [69] as part of oxide compounds such as silicon dioxide and is the most abundant element by mass in the Earth's crust.

  8. Dichlorine hexoxide - Wikipedia

    en.wikipedia.org/wiki/Dichlorine_hexoxide

    Dichlorine hexoxide is the chemical compound with the molecular formula Cl 2 O 6, which is correct for its gaseous state. However, in liquid or solid form, this chlorine oxide ionizes into the dark red ionic compound chloryl perchlorate [ClO 2] + [ClO 4] −, which may be thought of as the mixed anhydride of chloric and perchloric acids. This ...

  9. Valence (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Valence_(chemistry)

    The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.
