What is oxyanion?

Ion is a neutral atom or collection of atoms functioning as a unit. If the ion has an electrons deficit, it is a "cation", but if it has a surplus of electrons, it is an "anion". When oxygen is part of the cation, it is an oxycation - for example uranyl (Uo _{2 ) +2 . Alternatively, if oxygen atoms are part of the anion, it is an oxyanion such as nitrate (-no 3 2 ) (without 3 ) 2 .}

There are many varieties of oxyanion. These include sulphate (so _{4 ) -2 , acetate (ch 3 )}

-1 and Tellurite (Teo 3 )

-2 . Other types of Oxyanion include Charchloritant (CLO _{4 ) -1 , phosphate (after 4 )usually write as the corresponding acid from which it is derived. In this case, we have sulfur, acetic, permeable, chlorical and nitric acid. The removal of water from these acids gives anhydrides - sulfur dioxide, acetic anhydride, telurium oxide, chlorine heitxide, phosphorus pentoxide and pentoxide nitrogen. In particular, inorganic oxyanions often consist of oxygen plus non -carrier, such as sulfur, nitrogen or phosphorus; However, they can also consist of metal and oxygen.}

Two types of oxyanion containing metals are a dichromate and manganese. Potassium dichromant (K _{2 CR 2 o 7 ) is often used in organic chemical reactions as an oxidation agent; Persanganate potassium (KMNO 4 ) is even stronger oxidative oxidative. In combination with sulfuric acid, anhydride of persanganese acid or manganemheptoxide (mn 2 o 7 ), according to the reAction Equation 2 kmno 4 + H 2 SO 4 → K 2 Sat 4 + Mn 2 7 + h 2 o. Unlike the nature of the manganese, some oxyanion compounds at all act as oxidizers. The reason is a number of factors, including electronegativity, ion size, electron configuration and resonance stabilization.}

Electron configuration allowing the formation of oxyanion requires the presence of expandable electron orbital D-Shells that allow higher Valence atomic levels. Although three of the halogens, namely chlorine, bromine and iodine, have such shells and can also form highly oxygenated anions, not fluorine. It can form only one oxygen acid, pituitary acid, and it is so unstable that it easily explodes. Another factor that contributes to the creation and stability of Oxyanion is the ion resonance of symmetry. One of the most staconstruption of oxyanion, sulphate, sulphate can be drawn as one of the six possible equivalent resonant stsRunet, actually spreads a negative charge to a large outer surface.
