Anions in a sentence

For example, it is more difficult to oxidize sulfate anions than it is to oxidize bromide anions.

Hydrogen H + is exchanged for other cations, and carbonate (HCO 3 − ) and hydroxide (OH − ) anions are exchanged for nutrient anions.

Nomenclature of polyatomic anions There are two "rules" that can be used for learning the nomenclature of polyatomic anions.

Nickel, cobalt, and manganese enter the solution, where they are bound into stable complexes by the citric acid anions.

Although positively charged cations always move towards the cathode (hence their name) and negatively charged anions move away from it, cathode polarity depends on the device type, and can even vary according to the operating mode.

Because of the high polarity of the C-Na bonds, they behave like sources of carbanions (salts with organic anions ).

Because the superoxide releases the most energy when formed, the superoxide is preferentially formed for the larger alkali metals where the more complex anions are not polarised.

Beyond the classical Lewis bases and anions, all unsaturated molecules are also ligands, utilizing their pi electrons in forming the coordinate bond.

Biological role Fluoride anions are found in ivory, bones, teeth, blood, eggs, urine, and hair of organisms.

Chloride anions are essential to a large number of species, humans included.

Compounds LnQ 2 are known but these do not contain Ln IV but are Ln III compounds containing polychalcogenide anions.

Despite its name a chalcopyrite does not contain dianion pairs, but single S 2− sulfide anions.

Diazonium salts undergo a variety of useful transformations involving replacement of the N 2 group with anions.

Fluoride anions in very small amounts are essential for humans. citation There are 0.5 milligrams of fluorine per liter of human blood.

For highly electropositive elements, such as lithium and sodium, the carbon ligand exhibits carbanionic character, but free carbon-based anions are extremely rare, an example being cyanide.

Halogens While the halogens aren't nucleophilic in their diatomic form (i.e. I 2 is not a nucleophile), their anions are good nucleophiles.

However, some channels may be permeable to the passage of more than one type of ion, typically sharing a common charge: positive ( cations ) or negative ( anions ).

If an electrical potential (voltage) is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons.

In aqueous solution, tungstate gives the heteropoly acids and polyoxometalate anions under neutral and acidic conditions.

In the structure shown at right, the two pentagons are the cyclopentadienyl anions with circles inside them indicating they are aromatically stabilized.
