Halocline In oceanography, a halocline (from Greek hals, halo- ‘salt’ and klinein ‘to slope’) is a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water.Because salinity (in concert with temperature) affects the density of seawater, it can play a role in its vertical stratification.n certain high latitude regions (such as the Arctic Ocean, Bering Sea, and the Southern Ocean) the surface waters are actually colder than the deep waters and the halocline is responsible for maintaining water column stability-isolating the surface waters from the deep waters.

Organic Halogen Compounds Organic Halogen Compounds. Organic halogen compounds are a large class of natural and synthetic chemicals that contain one or more halogens (fluorine, chlorine, bromine, or iodine) combined with carbon and other elements. The simplest organochlorine compound is chloromethane, also called methyl chloride (CH 3 Cl).

- Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature-only as a compound. The most common of these being salt, or sodium chloride, and the potassium compounds sylvite (or potassium chloride) and carnallite (potassium magnesium chloride hexahydrate).

- Negative prefixes. Negative statements are the opposite of affirmative statements. In English, one way to make negative statements is by adding negative prefixes to nouns, adjectives, and verbs. Here are some English negative prefixes: a– , dis– , il– , im– , in- , ir– , non– , un– .

halogen Any of a group of five nonmetallic elements with similar properties. The halogens are fluorine, chlorine, bromine, iodine, and astatine. Because they are missing an electron from their outermost shell, they react readily with most metals to form salts. See Periodic Table.

Definitions &Translations Chloride. The chloride ion is formed when the element chlorine, a halogen, gains an electron to form an anion Cl−. The salts of hydrochloric acid contain chloride ions and can also be called chlorides. The chloride ion, and its salts such as sodium chloride, are very soluble in water.

Period 3 element Chlorine is a chemical element with symbol Cl and atomic number 17. It also has a relative atomic mass of 35.5. Chlorine is in the halogen group (17) and is the second lightest halogen following fluorine.The element is a yellow-green gas under standard conditions, where it forms diatomic molecules.Chlorine has the highest electron affinity and the third highest electronegativity of all the reactive elements.early all chlorine in the Earth's crust occurs as chloride in various ionic compounds, including table salt. It is the second most abundant halogen and 21st most abundant chemical element in Earth's crust. Elemental chlorine is commercially produced from brine by electrolysis.

Halide See also: Organic halide. A halide is a binary compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically ununseptide compound.

What is Salt in Chemistry? - Definition & Formula Chlorine is a non metal and is found in group 17 (7A) of the periodic table. It has seven valence electrons, and it needs just one more electron to achieve the magic eight stability! It does this by forming the Cl-anion.

Benzethonium chloride Benzethonium chloride, also known as hyamine is a synthetic quaternary ammonium salt. This compound is an odorless white solid, soluble in water. It has surfactant, antiseptic, and anti-infective properties, and it is used as a topical antimicrobial agent in first aid antiseptics.

Blizzard costs fliers big bucks Blizzard costs fliers big bucks. Blizzards cost airlines a ton of money -- but they actually hit passengers harder. The reason is simple: When airlines cancel flights they save on two of their biggest costs -- fuel and labor. But passengers end up spending more -- a lot more -- when a flight is canceled, on additional lodging and meals.

Salammoniac Sal ammoniac. Sal ammoniac is a rare mineral composed of ammonium chloride, NH4Cl. It forms colorless, white, or yellow-brown crystals in the isometric-hexoctahedral class. It has very poor cleavage and a brittle to conchoidal fracture. It is quite soft, with a Mohs hardness of 1.5 to 2, and it has a low specific gravity of 1.5.

Halocarbon Many synthetic organic compounds such as plastic polymers, and a few natural ones, contain halogen atoms; these are known as halogenated compounds or organic halides. Chlorine is by far the most abundant of the halogens in seawater, and the only one needed in relatively large amounts (as chloride ions) by humans.

Halogens on the Right Their chemical properties change just a little bit when compared to the element right above them on the table. The elements we are talking about in this section are called halogens. When a halogen combines with another element, the resulting compound is called a halide. One of the best examples of a halide is sodium chloride (NaCl). Don't think that the halogens always make ionic compounds and salts.

Haloalkane For more information, see Halomethane. Haloalkane or alkyl halides are the compounds which have the general formula RX where R is an alkyl or substituted alkyl group and X is a halogen (F, Cl, Br, I). Haloalkanes have been known for centuries. Chloroethane was produced synthetically in the 15th century.
