Polyatomic ion - Wikipedia Polyatomic ions often are useful in the context of acid–base chemistry and in the formation of salts Often, a polyatomic ion can be considered as the conjugate acid or base of a neutral molecule For example, the conjugate base of sulfuric acid (H 2 SO 4) is the polyatomic hydrogen sulfate anion (HSO− 4)
IUPAC nomenclature of inorganic chemistry - Wikipedia 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
Peroxide - Wikipedia The O−O group in a peroxide is often called the peroxide group, though some nomenclature discrepancies exist This linkage is recognized as a common polyatomic ion, and exists in many molecules
Silicate - Wikipedia Structure of the orthosilicate anion SiO4− 4 A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO(4−2x)− 4−x] n, where 0 ≤ x < 2 The family includes orthosilicate SiO4− 4 (x = 0), metasilicate SiO2− 3 (x = 1), and pyrosilicate Si2O6− 7 (x = 0 5, n = 2) The name is also used for any salt of such
Quaternary ammonium cation - Wikipedia Quaternary ammonium cation The R groups may be the same or different alkyl or aryl groups Also, the R groups may be connected In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR4]+, where R is an alkyl group, an aryl group [1] or organyl group Unlike the ammonium ion (NH+ 4) and the primary, secondary, or
Bicarbonate - Wikipedia In inorganic chemistry, bicarbonate (IUPAC -recommended nomenclature: hydrogencarbonate[2]) is an intermediate form in the deprotonation of carbonic acid It is a polyatomic anion with the chemical formula H C O − 3 Bicarbonate serves a crucial biochemical role in the physiological pH buffering system [3] The term "bicarbonate" was coined in 1814 by the English chemist William Hyde
Ion - Wikipedia 2 (peroxide, negatively charged, polyatomic) and He 2+ (alpha particle, positively charged, monatomic) [4] In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and a positive ion [5]
Sulfate - Wikipedia The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO42− Salts, acid derivatives, and peroxides of sulfate are widely used in industry Sulfates occur widely in everyday life Sulfates are salts of sulfuric acid and many are prepared from that acid
