  3. Oxyanion - Wikipedia

    en.wikipedia.org/wiki/Oxyanion

    Phosphate (PO 3− 4), sulfate (SO 2− 4), and perchlorate (ClO − 4) ions can be found as such in various salts. Many oxyanions of elements in lower oxidation state obey the octet rule and this can be used to rationalize the formulae adopted. For example, chlorine(V) has two valence electrons so it can accommodate three electron pairs from ...

  4. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.

    The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and ⁠ n + 2 / 2 ⁠. Pyrophosphate anion. Trimethyl ...

    The formal list is used. The name of the most electronegative element is modified to end in -ide and the more electropositive elements name is left unchanged. Taking the binary compound of sodium and chlorine: chlorine is found first in the list so therefore comes last in the name. Other examples are PCl 5 phosphorus pentachloride

  7. Phosphorus oxoacid - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_oxoacid

    In chemistry, phosphorus oxoacid (or phosphorus acid) is a generic name for any acid whose molecule consists of atoms of phosphorus, oxygen, and hydrogen. [1] There is a potentially infinite number of such compounds. Some of them are unstable and have not been isolated, but the derived anions and organic groups are present in stable salts and ...

    Ⓚ Of 103 elements shown in the image, just ten form anions, all of these being in the p-block: arsenic; the five chalcogens: oxygen, sulfur, selenium, tellurium, polonium; and the four halogens: fluorine, chlorine, bromine, and iodine Ⓛ Anion-only elements are confined to oxygen and fluorine.

    The cation is always named first. Ions can be metals, non-metals or polyatomic ions. Therefore, the name of the metal or positive polyatomic ion is followed by the name of the non-metal or negative polyatomic ion. The positive ion retains its element name whereas for a single non-metal anion the ending is changed to -ide.
