Anion Table - Revised 2009-2010
This list does not include anions you can get directly from the Periodic Table

Phosphate, PO₄^3-
Phosphite, PO₃^3-
Acetate, C₂H₃O₂^1-
Sulfite, SO₃^2-
Sulfate, SO₄^2-
Carbonate, CO ₃^2-
Nitrite, NO₂^1-
Nitrate, NO₃^1-
Hydroxide, OH^1-
Chlorite, ClO₂^1-
Chlorate, ClO₃^1-
Chromate, CrO₄^2-
Peroxide, O₂^2-
Cyanide, CN^1-
Permanganate, MnO₄^1-

PLUS ONE CATION POLYATOMIC IONS: Ammonium NH₄¹⁺

Help For Memorizing in Two Sets
1st Set: Phosphate (PO₄^3-), Sulfate (SO₄^2-), Nitrate (NO₃^1-), Chlorate (ClO₃^1-)

2nd Set: Phosphite (PO₃^3-), Sulfite (SO₃^2-), Nitrite (NO₂^1-), Chlorite (ClO₂^1-)
NOTE: ONLY DIFFERENCE IS -ATE HAS ONE MORE OXYGEN ATOM THAN -ITE.

1st Set:Ammonium (NH₄¹⁺), Carbonate (CO ₃^2-), Hydroxide (OH^1-), Cyanide (CN^1-),

2nd Set: Chromate (CrO₄^2-), Peroxide (O₂^2-), Acetate (C₂H₃O₂^1-), Permanganate (MnO₄^1-)

GENERAL NOTE: -ITE AND -ATE MEANS ELEMENT & OXYGEN ARE COVALENTLY BONDING IN POLYATOMIC ION. -IDE IS ION THAT ONLY HAS ELEMENT.
