The following are list of polyatomic ions. These might be advantageous when perfect ChemSkill Builder and Homework problems. The exams will incorporate only the nine us have focused on:
|The 9 polyatomic ion to know and write on her notecard: |
|Name ||Charge ||Formula |
|Hydroxide ||1- ||OH- |
|Cyanide ||1- ||CN- |
|Nitrate ||1- ||NO3- |
|Acetate ||1- ||CH3COO- |
|Carbonate ||2- ||CO32- |
|Phosphate ||3- ||PO43- |
|Hydronium ||1+ ||H3O+ |
|Ammonium ||1+ ||NH4+ |
|Sulfate ||2- ||SO42- |
Other polyatomic ions:
|bicarbonate (hydrogen carbonate)||HCO31-|
|bisulfate (hydrogen sulfate)||HSO41-|
|dihydrogen phosphate||H2PO41- |
|hydrogen lead carbonate (bicarbonate)||HCO31-|
** exemption to prefix rulesNOTE: -ite ending way one less oxygen than the -ate form. PREFIXES: per- = one much more oxygen 보다 -ate hypo- = one much less oxygen 보다 -ite
Ions arranged by familyPolyatomic cations other than ammonium, hydronium, and mercury(I) aren\"t typically encountered in general chemistry. Most common polyatomic anions occur in \"families\". Every members the the household share the same main element and the same charge. There room three common types of variations within the family: Different members of the family can have actually numbers the oxygens. Each member that the family can integrate with hydrogen ion to partially neutralize their negative charge. Part members the the household can have sulfur substituted because that oxygen. Various other variations exist but are much less common.

alternative names are offered in italics. Pick the name of the ion for information about its occurrence, uses, properties, and also structure. Blank entries room uncommon or unstable; for a finish table check out the field Guide to Polyatomic Ions.

|If you can remember the formula that the ion whose surname ends with ate, friend canusually job-related out the recipe of the other household members together follows: |
modify stem surname with:Some anions can record hydrogen ions. Because that example, carbonate (CO32- can catch an H+ to produce hydrogen carbonate HCO3- (often referred to as bicarbonate). Each captured hydrogen neutralizes one minus fee on the anion.
|-ate||a typical form, include oxygen ||chlorate, ClO3-nitrate, NO3-sulfate, SO42-|
|-ite||one much less oxygen 보다 -ate form||chlorite, ClO2-sulfite, SO32-nitrite, NO2- |
|per-, -ate||same charge, but contains one more oxygen 보다 -ate form||perchlorate, ClO4-perbromate, BrO4- |
|hypo-, -ite||same charge, but contains one less oxygen 보다 the -ite form||hypochlorite, ClO-hypobromite, BrO- |
|thio-||replace one O with an S||thiosulfate, S2O32-thiosulfite, S2O22-|

Table of usual polyatomic cations, i ordered it by charge. alternate names are provided in italics. Select the surname of the ion for information around its occurrence, uses, properties, and also structure.
|Hg22+||mercury(I) or mercurous|
|HCO3-||hydrogen carbonate or bicarbonate|
|HSO4-||hydrogen sulfate or bisulfate|
|Hydrogen Sulfate HSO4-|
|Hydrogen Phosphate HPO42-|
Polyatomic formulas - Polyatomic ions space made from an ext that one atom. This group of atom act together as one unit through a single charge. Each of the polyatomic ions have a distinctive name.
Table the Polyatomic ion
|ammonium , NH4 +||acetate, C2H302-||carbonate, CO32-||phosphate, PO43-|
|bicarbonate, HCO3 -||chromate,CrO42-|
|bisulfate, HSO4 -||dichromate,Cr2O72-|
|bisulfite, HSO3 -||oxalate,C2O42-|
Most of the polyatomic ions space anions. The formula because that the compound will contain both a cation and also an anion to balance the overall charge the the compound.

The cation is named normally and also the anion is provided the surname of the really anion. One easy means to acknowledge these recipe is the fact that they are comprised of more that two facets and, usually, the an initial element is a metal.
