A List of Common Polyatomic Ions With Charges and Oxidation Numbers. List Of Polyatomic Ions. Positively charged ions are called cations and negatively charged ions are called anions. No notes, all the positive ions including the polyatomic ions, all the -1 monatomic ions and the -3 polyatomic ion are missing. Such charged atoms, called ions, are formed by the addition or removal of electrons. This list of interferences is not intended to be complete, but does cover those more frequently reported. Polyatomic ions are groups of atoms that bear net electrical charges, although the atoms in a polyatomic ion are held together by the same covalent bonds that hold atoms together in molecules. ammonium - NH 4 + Polyatomic Ion Charge = -1 . î t Ö0 ÿ ÿ ÿ ÿ ÿ ÿ ö 6ö ö Ö ÿ ÿÖ ÿ ÿÖ ÿ ÿÖ ÿ ÿ4Ö C2H3O2-1 or CH3COO-1 acetate NH3 ammonia NH4+1 ammonium ion HCO3-1 bicarbonate or hydrogen carbonate BO3-3 borate CO3-2 carbonate ClO3-1 chlorate ClO2-1 chlorite CrO4-2 chromate CN-1 cyanide Cr2O7-2 dichromate HCO3-1 Hydrogen carbonate or bicarbonate Make sure you are familiar with the most common polyatomic ions.
