This is part 2 of the Chemistry help. Part one gave a list of Element Symbols you should check out!
I know some of you ask, "What are polyatomic ions?" Polyatomic ions are chemically charged molecules consisting of two or more atoms connected usually by a covalent bond. Here are the Polyatomic ions you should know. They are organized by charges:
1+:
Ammonium- NH4+
Hydronium- H3O+
1-:
Acetate- C2HO2-
Chlorate- CIO3-
Chlorite- CIO2-
Cyanide- CN-
Dihydrogen Phosphate- H2PO4-
Hydrogen Carbonate or bicarbonate- HCO3-
Hydrogen Sulfite or Bisulfite- HSO3-
Hydroxide- OH-
Hydrochlorite- CIO-
Nitrite- NO2-
Nitrate- NO3-
Perchlorate- CIO4-
Permanganate- MnO4-
Thiocyanate- SCN-
Hypobromite- Bro-
Bromite- BrO2-
Bromate- BrO3-
Perbromate- BrO4-
Hypoiodite- IO-
Iodite- IO2-
Iodate- IO3-
Periodate- IO4-
2-:
Carbonate- CO32-
Chromate- CrO42-
Dichromate- Cr2O72-
Hydrogen Phosphate- HPO42-
Oxalate- C2O42-
Peroxide- O22-
Sulfate- SO42-
Sulfite- SO32-
Silicate- SiO32-
3-:
Arsenate- AsO43-
Phosphate- PO43-
Phosphite- PO33-
Borate- BO33-
If you remember these easy ions and symbols, Chemistry will be a lot more relaxing and fun (especially if you are taking AP Chemistry)!!
