<center>Anion Table - Revised 2009-2010</center> 
This list does not include anions you can get directly from the Periodic Table 
*Phosphate, PO43- 
*Phosphite, PO33- 
*Acetate, C2H3O21- 
*Sulfite, SO32- 
*Sulfate, SO42- 
*Carbonate, CO 32- 
*Nitrite, NO21- 
*Nitrate, NO31-
*Hydroxide, OH1-
*Chlorite, <nowiki>ClO</nowiki>21-
*Chlorate, <nowiki>ClO</nowiki>31- 
*Chromate, <nowiki>CrO</nowiki>42-
*Peroxide, O22-
*Cyanide, <nowiki>CN</nowiki>1- 
*Permanganate, <nowiki>MnO</nowiki>41-
PLUS ONE CATION POLYATOMIC IONS: Ammonium <nowiki>NH</nowiki>41+ 
------- 
<center>Help For Memorizing in Two Sets</center> 
1st Set: Phosphate (PO43-), Sulfate (SO42-), Nitrate (NO31-), Chlorate (<nowiki>ClO</nowiki>31-)

2nd Set: Phosphite (PO33-), Sulfite (SO32-), Nitrite (NO21-), Chlorite (<nowiki>ClO</nowiki>21-) 
NOTE: ONLY DIFFERENCE IS -ATE HAS ONE MORE OXYGEN ATOM THAN -ITE.

1st Set:Ammonium (<nowiki>NH</nowiki>41+), Carbonate (CO 32-), Hydroxide (OH1-), Cyanide (<nowiki>CN</nowiki>1-), 
 
2nd Set: Chromate (<nowiki>CrO</nowiki>42-), Peroxide (O22-), Acetate (C2H3O21-), Permanganate (<nowiki>MnO</nowiki>41-) 
 
GENERAL NOTE: -ITE AND -ATE MEANS ELEMENT & OXYGEN ARE COVALENTLY BONDING IN POLYATOMIC ION. -IDE IS ION THAT ONLY HAS ELEMENT.
